flora family asteroid

Regardless of your location on the Earth, 8 Flora will reach its highest point in the sky around midnight local time. Stervormig families zichtbaar als afzonderlijke concentraties bij asteroïden uitgezet in de juiste baanelement ruimte ( … We created an initial Flora family and followed test asteroids 1 and 3 km in diameter using a numerical code that accounted for both planetary perturbations and nongravitational effects. Lightcurve analysis indicates that Flora's pole points towards ecliptic coordinates (β, λ) = (16°, 160°) with a 10° uncertainty. Our Flora family members reproduce the observed semimajor axis, eccentricity, and inclination distributions of the real family after to 1.4 Gyr. Flora, and the whole Flora family generally, are good candidates for being the parent bodies of the L chondrite meteorites. From Redmond, it will be visible between 20:02 and 04:07.It will become accessible around 20:02, when it rises to an altitude of 21° above your eastern … Flora was discovered in 1847 and named for the Latin goddess of gardens and flowers. There is also a scattered group of objects in the general vicinity of the Vesta family but not part of it. The Flora asteroid family, which resides in the innermost region of the main asteroid belt, has been known for nearly a century. the WAM analysis by Zappala 1995). [4] This gives an axial tilt of 78°, plus or minus ten degrees. The distribution of proper elements and physical properties of Flora-family asteroids are compared with those of families believed to have formed from the catastrophic disruption of parent bodies. Minor planet numbers are also given to objects of the Kuiper belt, which is similar to the asteroid belt but farther out around 30–60 AU, whereas asteroids are mostly between 2–3 AU from the Sun and at the orbit of Jupiter 5 AU from the Sun. [11] Flora had come to opposition on 1917 February 13, 40 days earlier. It is the seventh brightest asteroid with a mean opposition magnitude of +8.7. 8 Flora is a big, bright, main belt asteroid.It is the closest big asteroid: no asteroid closer to the Sun has a diameter above 25 kilometres or two-elevenths that of Flora itself, and not until the tiny 149 Medusa was found was a single asteroid orbiting at a closer mean distance known. Contents[show] General properties Large, prominent families contain several hundred recognized asteroids (and many more smaller objects which … The last remaining lost asteroid, 69230 Hermes, was recovered in 2003. In extreme cases such as the Flora family, the degree of dispersion and the presence of a … 2007), 1514 Ricouxa, and 1682 Karel in the … The Flora family is one of the asteroid families that were discovered early (Hirayama, 1918). Flora's the largest, inner main belt asteroid with a diameter of about 91 miles (147 km) or about the size of Connecticut. 2007, Nature, 449, 48-53). In recent years, the distribution of orbital elements within an asteroid family has been shown to be affected both by the Yarkovsky effect and by passage across weak planetary resonances (e.g., Nesvorny et al. It is the innermost large asteroid: no asteroid closer to the Sun has a diameter above 25 kilometres or two-elevenths that of Flora itself, and not until the tiny 149 Medusa was discovered was a single asteroid orbiting at a closer mean distance known. The Flora Family Foundation was established in 1998 by the family of William R. Hewlett (co-founder of the Hewlett-Packard Company) and his wife Flora Lamson Hewlett. Because of its poorly defined boundaries, and the location of Flora itself near the edge, this asteroid group has also sometimes been called the Ariadne family, … 43 Ariadne makes up much of the remaining mass (about a further 9%, with the remaining family members being fairly small, below 30 km in diameter. Download Citation | Photometry of 16 Flora family asteroids (Kryszczynska, 2013) | The files contain asteroid brightness and geometry for corresponding … The Flora family is a collection of asteroids near the inner edge of the asteroid belt whose orbits have semimajor axes of 2.12 to 2.25 AU and mean inclinations of about 5°. Asteroid families are believed to originate by catastrophic disruptions of large asteroids. Jenniskens speculates the Chelyabinsk rock belonged to a larger "rubble pile" asteroid that broke apart 1.2 million years ago, possibly after a close encounter with Earth's gravitational pull. Ingrid is a member of the Flora family , a giant asteroid family and the largest family of stony asteroids. This page was last changed on 19 January 2021, at 02:36. The Flora family of asteroids is a large grouping of S-type asteroids in the inner main belt, whose origin and properties are relatively poorly understood at present.Roughly 4-5% of all main belt asteroids belong to this family. In some countries this may not be legally possible; if so: Nevertheless, the parent body was almost for sure destroyed by the impact/s that made the family, and Flora is probably a gravitational aggregate of most of the pieces.[source?] Though di use, the family associated with asteroid (8) Flora dominates the inner main belt in terms of the extent of its members in orbital parameter space, result- … The families are thought to form as a result of collisions between asteroids. Nor is it plausible that a rogue comet somehow became captured into asteroid … All the members of the Flora family probably came from the breakup of a single parent body; however, other asteroids in this region with similar orbital characteristics appear to have different origins. But P/2013 P5 probably isn't a comet. See the latest details. Methods. Asteroids are given minor planet numbers, but not all minor planets are asteroids. In recent years, the distribution of orbital elements within an asteroid family has been shown to be affected both by the Yarkovsky effect and by passage across weak planetary resonances (e.g., Nesvorny et al. The Flora family is one of the asteroid families that were discovered early (Hirayama, 1918). These include: 809 Lundia — Orbits within the Flora family region; 956 Elisa; 1459 Magnya — Orbits in the outer asteroid belt, too far from Vesta to be genetically related. The proper elements are analytically defined as constants of motion of a suitably simplified dynamical system. Orbit and classification. 951 Gaspra / ˈ ɡ æ s p r ə / is an S-type asteroid that orbits very close to the inner edge of the asteroid belt.Gaspra was discovered by Russian astronomer G. N. Neujmin in 1916. Neujmin named it after Gaspra, a Black Sea retreat that was visited by his contemporaries, such as Gorky and Tolstoy.. Gaspra was the first asteroid ever to be closely approached when it was visited … [citation needed]A large proportion have orbital elements similar to those of 4 Vesta, either close enough to be part of the Vesta family, or having similar eccentricities and inclinations but with … Earlier work by Bill Bottke, a planetary scientist at the Southwest Research Institute, has fingered one such asteroid family as the birthplace of the dinosaur-killer and accused another, the Flora family, of causing impacts on Earth perhaps a billion years ago. Though di use, the family associated with asteroid (8) Flora dominates the inner main belt in terms of the extent of its members in orbital parameter space, result- … This is because unrelated asteroids are hard to distinguish from family members because the family is of the same spectral type (S) that dominates the closer main belt overall. 1), a little narrower than the values adopted by the other studies.Considered that other asteroid families may exist around the region where the Flora family resides, in the condition that a sufficient number of sample members … Some families (e.g. The Flora family, one of the largest with more than 800 known members, may have formed from a collision less than a billion years ago. Flora family – A prominent family of stony asteroids with an albedo of 0.24. This applies worldwide. In a series of numerical simulations, we explore the effect on the Flora family orbital distribution of res-onances alone (Section 3), close approaches to the most massive asteroids (Appendix), and the interplay between Yarkovsky and resonant affects (Section 4). Asteroid 8 Flora. These factors suggest that Flora may be a primary source of … This makes sense because it's the largest member of the Flora family, a group of more than 13,000 asteroids that share similar orbits. It is 2.3 times farther from … From Simple English Wikipedia, the free encyclopedia, Asteroid Families: Search of a 12,487-Asteroid Sample Using Two Different Clustering Techniques, https://simple.wikipedia.org/w/index.php?title=Flora_family&oldid=7289192, Articles with unsourced statements from February 2007, Creative Commons Attribution/Share-Alike License. The family of asteroids Flora Licence Public domain Public domain false false: I, the copyright holder of this work, release this work into the public domain. Curiously, our understanding of its properties has remained fairly murky even as our knowledge of the asteroid belt has increased. Several new studies on the Feb. 15 meteor explosion over Chelyabinsk, Russia, has revealed a much higher asteroid risk to Earth than previously thought, scientists say. Aims. Van Wikipedia, de gratis encyclopedie. In extreme cases such as the Flora family, the degree of dispersion and the presence of a significant … Our results suggest that the Flora family dynamically disperses on a few 10 8 -year time scale and that its age may be significantly less than 10 9 years. Planetoïdenfamilie - Asteroid family. About 4-5% of all main belt asteroids belong to this family. Objects in this region, when pushed onto planet-crossing orbits, tend to have relatively high probabilities of striking the Earth. [7] It is the seventh-brightest asteroid with a mean opposition magnitude of +8.7. All the members of the Flora family probably came from the breakup of a single parent body; however, other asteroids in this region with similar orbital characteristics appear to have different origins. It is the innermost large asteroid: no asteroid closer to the Sun has a diameter above 25 kilometres or two-elevenths that of Flora itself, and not until the tiny 149 Medusa was discovered was a single asteroid orbiting at a closer mean distance known. James Baer, Steven Chesley & Robert Matson (2011) "Astrometric masses of 26 asteroids and observations on asteroid porosity.". This is a shape model of Flora computed using light curve inversion techniques. [9], Flora was discovered by J. R. Hind on 18 October 1847. Request PDF | On Jan 1, 2008, A. Kryszczynska and others published Physical Investigations of the Flora Family Asteroids | Find, read and cite all the research you need on ResearchGate Because of its poorly defined edges, and the location of Flora itself near the edge, this asteroid group has also sometimes been called the Ariadne family, when Flora … The few unrelated asteroids that have been found are all small (Florczak et al. We created an initial Flora family and followed test asteroids 1 and 3 km in diameter using a numerical code that accounted for both planetary perturbations and nongravitational effects. en These concentrations are the asteroid families. Its location in the inner main belt makes their members available for photometric and spec-troscopic observations even for small telescopes. The orbit of the asteroid could make it a member of the Flora asteroid family. Flora's spectrum indicates that its surface composition is a mixture of silicate rock (including pyroxene and olivine) and nickel-iron metal. The family name is based on the name or provisional designation of the largest member of the family. Evidence is presented indicating that the Flora family is of common origin. [10] This meteorite type comprises about 38% of all meteorites impacting the Earth. Because of its poorly defined edges, and the location of Flora itself near the edge, this asteroid group has also sometimes been called the Ariadne family, when Flora did not make it into the group during an analysis (e.g. It's also one of the brightest. Our Flora family members reproduce the observed semimajor axis, eccentricity, and inclination distributions of the real family after to 1.4 Gyr. The biggest member is 8 Flora, which mesures 140 km in diameter, and takes up about 80% of the total family mass. the Vesta, Pallas, Hygiea, and Massalia families). The Flora family of asteroids is a big group of S-type asteroids in the closer part of the main belt, whose origin and properties are not well understood right now. 2007, Nature, 449, 48-53). The purpose of the Foundation is to promote the well-being of people everywhere by supporting selected activities of charitable organizations and institutions as determined by members of the Board and Family … Flora's the largest, inner main belt asteroid with a diameter of about 91 miles (147 km) or about the size of Connecticut. It was his second asteroid discovery after 7 Iris. She distinguished prograde and retrograde groups of as-teroidsandreportedan excessofprograderotators. Jenniskens calculated the Chelyabinsk object may have come from the Flora asteroid family in the inner asteroid belt. It is the seventh brightest asteroid with a mean opposition magnitude of +8.7. In 1918, the Japanese astronomer K. Hirayama first recognized some non random concentrations of asteroid elements. However, few have been found. At 81.7 million miles (131.4 million km) away, it's almost 21 times closer and completes an orbit in 3.3 years compared to the ice giant's 84 years. Flora can reach a magnitude of +7.9 at a favorable opposition near perihelion Flora is the parent body of the Flora family of asteroids, and by far the largest member, comprising about 80% of the total mass of this family. NESVORNY SYNTHETIC FAMILY NAME * The name of the asteroid family in the Nesvorny family analysis based on synthetic proper elements. For one thing, it's in an orbit shared by the Flora family of asteroids, which formed roughly 200 million years ago, so it's likely just a chip off this grouping's parent body. Less than a dozen degrees southeast of Uranus, you'll find the main belt asteroid 8 Flora. Asteroid 8 Flora is currently in the constellation of Cetus.The current Right Ascension of Asteroid 8 Flora is 02h 39m 46s and the Declination is +10° 16’ 14” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom []).The current magnitude of Asteroid 8 Flora is 9.79 (JPL). Because of its poorly defined edges, and the location of Flora itself near the edge, this asteroid group has also sometimes been called the Ariadne family, when Flora … Flora may be the residual core of an intensely heated, thermally evolved, and magmatically differentiated planetesimal which was subsequently disrupted. [citation needed], The name Flora was proposed by John Herschel, from Flora, the Latin goddess of flowers and gardens, wife of Zephyrus (the personification of the West wind), and mother of Spring. Especially, the orbit and spin characteristics can reflect the influences of the Yarkovsky effect and the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect on the evolution of the asteroid family, respectively. Formed from a catastrophic collision of a parent body larger than 150 km in diameter, the Flora family is located in the innermost part of the main belt near the {ν } 6 secular resonance. [citation needed]. Example sentences with "asteroid family", translation memory. An asteroid family is a group of minor planets that share similar orbital elements, such as semimajor axis, eccentricity, and orbital inclination. 8 Flora is a big, bright, main belt asteroid.It is the closest big asteroid: no asteroid closer to the Sun has a diameter above 25 kilometres or two-elevenths that of Flora itself, and not until the tiny 149 Medusa was found was a single asteroid orbiting at a closer mean distance known. The Flora family is the asteroid family proposed by Hirayama in the last century, following the Koronis, Eos and Themis asteroid families 4, 5. Formally known as 1979 MB4, this is a 2km-wide asteroid of the Flora family in the asteroid belt’s inner region. Differences in these orbital and physical properties suggest that the creation of the Flora family was more … among Flora family asteroids. Asteroid families are the remnants of the catastrophic collision, and their fundamental physical properties provide us the information of their parent bodies and evolutions. Another study of rotational states in an asteroid family was performed by Kryszczynska (2013), who focused on the Flora´ family. The Flora asteroid family, which resides in the innermost region of the main asteroid belt, has been known for nearly a century. 1998, and also by inspection of the PDS asteroid taxonomy data set for non S-type members.) The Greek equivalent is Chloris, who has her own asteroid, 410 Chloris, but in Greek Flora is also called Chloris (8 Χλωρίς). The influence of the Yarkovsky and YORP effects should be observable among objects in asteroid families, especially in the Flora family, which lies close to the Sun and consists of many small objects. Many S-type asteroids have similar compositions and spectral characteristics with certain meteorites. The Flora family is a collection of asteroids near the inner edge of the asteroid belt whose orbits have semimajor axes of 2.12 to 2.25 AU and mean inclinations of about 5°. They are nowadays identified as clusters in the proper orbital elements space. Flora (minor planet designation: 8 Flora) is a large, bright main-belt asteroid. We can therefore conclude that the Flora subfamilies are probably of common origin but that if this family resulted from the dis ruption of a single parent body then either: (a) the shape of that body was far from spherical, or (b) if proto-Flora were spheri cal (D -v 210 km) then the present Flora family contains only approximately one-half the mass of the parent asteroid. Whoa — that's a lot of relatives! The Flora family of asteroids is a large grouping of S-type asteroids in the inner main belt, whose origin and properties are relatively poorly understood at present.Roughly 4-5% of all main belt asteroids belong to this family. [11][12], On 26 July 2013, Flora at magnitude 8.8 occulted the star 2UCAC 22807162 over parts of South America, Africa, and Asia.[13]. 402 8 Flora The spectra of the V-type asteroids, or vestoids, are similar to that of 4 Vesta, by far the largest asteroid in this class (hence the name). Forming the Flora Family: Implications for the Near-Earth Asteroid Population and Large Terrestrial Planet Impactors David Vokrouhlický1, William F. Bottke2, and David Nesvorný2 1 Institute of Astronomy, Charles University, V Holešovičkách 2, CZ–18000 Prague 8, Czech Republic; vokrouhl@cesnet.cz 2 Department of Space Studies, Southwest Research Institute, … add example. It is the seventh-brightest asteroid with a mean … Asteroid Flora. Formed from a catastrophic collision of a parent body larger than 150 km in diameter, the Flora family is located in the innermost part of the main belt near the {ν } 6 secular resonance. Flora Asteroids: 951 Gaspra, 8 Flora, Flora Family, 43 Ariadne, 9913 Humperdinck, 291 Alice, (9928) 1981 We9, 4065 Meinel, 281 Lucretia: Books, LLC, Books, LLC: Amazon.nl In the 1968 science-fiction film The Green Slime, an orbital perturbation propels the asteroid Flora into a collision course with Earth. Curiously, our understanding of its properties has remained fairly murky even as our knowledge of the asteroid belt has increased.

Indeed, they are generally nearly constant on a 10 7 -10 8-year time scale. The largest among them is associated with (8) Flora. Such cratering families typically consist of a single large body and a swarm of asteroids that are many times smaller. Forming the Flora Family: Implications for the Near-Earth Asteroid Population and Large Terrestrial Planet Impactors 2017, AJ, 153 , 172 Vokrouhlicky, D., and 12 colleagues: They include 298 Baptistina, 422 Berolina, 2093 Genichesk, 2259 Sofievka (the biggest, with a 21 km diameter), 2952 Liliputia, 3533 Toyota, 3850 Peltier, 3875 Staehle, 4278 Harvey, 4396 Gressmann, and 4750 Mukai. The Flora family, being located near the inner edge of the main asteroid belt, is one of the largest asteroid families in … en The results showed that for both asteroid families, generally the most precise version of the algorithm was the topocentric version. the Flora family) have complex intern… The members of the families are thought to be fragments of past asteroid collisions. [8] Flora can reach a magnitude of +7.9 at a favorable opposition near perihelion, such as occurred in November 2007. Nevertheless, Flora was almost certainly disrupted by the impact(s) that formed the family, and is probably a gravitational aggregate of most of the pieces. Approximately 6% of main-belt asteroids are vestoids. Asteroid 8 Flora will be well placed, lying in the constellation Cetus, well above the horizon for much of the night.. [11] This mistake was uncovered only in 1995. We discuss the possibility that the parent bodies of the Flora family and of the ordinary L … This splitting It accounts for 15–20% of the main belt as- teroids with 2.1< a <2.5 AU. It's about 147 kilometers across — comparable in size to the state of Connecticut — and the largest asteroid in the inner main belt. It is the seventh-brightest asteroid with a mean opposition magnitude of +8.7. Flora family The Flora family of asteroids is a big group of S-type asteroids in the closer part of the main belt , whose origin and properties are not well understood right now. It orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 5 months (1,237 days). [citation needed]. Again, one of the largest families with more than 13.000 members, or about 3.5% of all main-belt asteroids. This family has a lot of members and is dynamically dispersed in eccentric-ity and inclination. It is located in the inner region of the asteroid belt. 2156 Kate, identified by one of the clustering method and dif- Three additional, already known spin vectors for 951 Gaspra ferent than S taxonomic type, which are probable interlopers in (all determinations collected at the Poznan Observatory web- the Flora family, were also excluded, because asteroid families site, Kryszczynska et al. es Estas concentraciones son las familias de asteroides. young collisional family within the Koronis family was born Slivan & Molnar 2012). Analysis of the rock suggests it was apparently exposed to cosmic rays for only about 1.2 million years, unusually short for rocks originating in the Flora family. Objects in this region, when pushed onto planet-crossing orbits, tend to have relatively high probabilities of striking the Earth. Flora (minor planet designation: 8 Flora) is a large, bright main-belt asteroid. About 4-5% of all main belt asteroids belong to this family. Because of the high background density of asteroids in this part of space, one might expect that a great number of asteroids unrelated to the collision that made the family would be present. It is a remnant from a collisional disruption of a large body or bodies that occurred hundreds of My to a few Gy ago (the age of the family was approximated by several authors, for example WikiMatrix. Flora asteroid family: Number of members ~ 819, Largest member: 8 Flora, 136km, Average distance from Sun: 2.169 -2.211 AU's. Flora (minor planet designation: 8 Flora) is a large, bright main-belt asteroid.It is the innermost large asteroid: no asteroid closer to the Sun has a diameter above 25 kilometres or two-elevenths that of Flora itself, and not until the tiny 149 Medusa was discovered was a single asteroid orbiting at a closer mean distance known. 2002, Icarus, 157, 155-172; Bottke et al. During an observation on 25 March 1917, 8 Flora was mistaken for the 15th-magnitude star TU Leonis, which led to that star's classification as a U Geminorum cataclysmic variable star. In many or most cases the parent body was shattered, but there are also several families which resulted from a large cratering event which did not disrupt the parent body (e.g. Age: 500 million - 1 billion years. PRELIMINARIES ON THE FLORA FAMILY The inner zone of the asteroid belt is characterized by the presence of three populous clans (named Flora, Nysa, and Vesta in Zappal`aet al.1994). The Flora family of asteroids is a big group of S-type asteroids in the closer part of the main belt, whose origin and properties are not well understood right now.About 4-5% of all main belt asteroids belong to this family. The largest asteroid to be a true member of a family (as opposed to an interloper in the case of Ceres with the Gefion family) is 4 Vesta. The Flora family of asteroids is a big group of S-type asteroids in the closer part of the main belt, whose origin and properties are not well understood right now.About 4-5% of all main belt asteroids belong to this family. Because of its poorly defined boundaries, and the location of Flora itself near the edge, this asteroid group has also sometimes been called the Ariadne family, … Available evidence concerning the Flora family, together with recent models for the collisional evolution of the asteroids, suggests that this family may have originated from a binary or multiple asteroid. It is a remnant from a collisional disruption of a large body or bodies that occurred hundreds of My to a few Gy ago (the age of the family was approximated by several authors, for example The Flora asteroid family members defined by the LCDB are distributed in the semi-major axis interval of a ∈ [2.15, 2.35] au (as shown in Fig. 2002, Icarus, 157, 155-172; Bottke et al. This means that it is probably a piece from an asteroid collision that occurred roughly 200 million years ago.
