Many S-type asteroids have similar compositions and spectral characteristics with certain meteorites. young collisional family within the Koronis family was born Slivan & Molnar 2012). Evidence is presented indicating that the Flora family is of common origin. 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. [4] This gives an axial tilt of 78°, plus or minus ten degrees. About 4-5% of all main belt asteroids belong to this family. the WAM analysis by Zappala 1995). [8] Flora can reach a magnitude of +7.9 at a favorable opposition near perihelion, such as occurred in November 2007. 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. It's about 147 kilometers across — comparable in size to the state of Connecticut — and the largest asteroid in the inner main belt. 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. Asteroid 8 Flora. [9], Flora was discovered by J. R. Hind on 18 October 1847. Flora was discovered in 1847 and named for the Latin goddess of gardens and flowers. 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. 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. In extreme cases such as the Flora family, the degree of dispersion and the presence of a significant … Asteroid families are believed to originate by catastrophic disruptions of large asteroids. We discuss the possibility that the parent bodies of the Flora family and of the ordinary L … 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°. The orbit of the asteroid could make it a member of the Flora asteroid family. The Flora asteroid family, which resides in the innermost region of the main asteroid belt, has been known for nearly a century. Flora (minor planet designation: 8 Flora) is a large, bright main-belt asteroid. Planetoïdenfamilie - Asteroid family. 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- … 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. Binsel, Richard P.; Gehrels, Tom and Matthews, Mildred Shapley (editors); "JPL Small-Body Database Browser: 8 Flora", "AstDyS-2 Flora Synthetic Proper Orbital Elements", "Announcement of discovery of Flora", MNRAS, https://en.wikipedia.org/w/index.php?title=8_Flora&oldid=1000632173, Articles with dead external links from February 2019, Articles with permanently dead external links, Articles with dead external links from June 2017, Articles with unsourced statements from October 2020, Articles with unsourced statements from November 2008, Creative Commons Attribution-ShareAlike License, This page was last edited on 16 January 2021, at 00:14. 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 accounts for 15–20% of the main belt as- teroids with 2.1< a <2.5 AU. This page was last changed on 19 January 2021, at 02:36. 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. Asteroids are given minor planet numbers, but not all minor planets are asteroids. About 4-5% of all main belt asteroids belong to this family. They are nowadays identified as clusters in the proper orbital elements space. Another study of rotational states in an asteroid family was performed by Kryszczynska (2013), who focused on the Flora´ family. Less than a dozen degrees southeast of Uranus, you'll find the main belt asteroid 8 Flora. These factors suggest that Flora may be a primary source of … Curiously, our understanding of its properties has remained fairly murky even as our knowledge of the asteroid belt has increased. Differences in these orbital and physical properties suggest that the creation of the Flora family was more … Flora's the largest, inner main belt asteroid with a diameter of about 91 miles (147 km) or about the size of Connecticut. But P/2013 P5 probably isn't a comet. 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. The families are thought to form as a result of collisions between asteroids. 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, … 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. The Greek equivalent is Chloris, who has her own asteroid, 410 Chloris, but in Greek Flora is also called Chloris (8 Χλωρίς). 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. 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 It is the seventh brightest asteroid with a mean opposition magnitude of +8.7. An asteroid family is a group of minor planets that share similar orbital elements, such as semimajor axis, eccentricity, and orbital inclination. Flora family – A prominent family of stony asteroids with an albedo of 0.24. Flora can reach a magnitude of +7.9 at a favorable opposition near perihelion Van Wikipedia, de gratis encyclopedie. 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. James Baer, Steven Chesley & Robert Matson (2011) "Astrometric masses of 26 asteroids and observations on asteroid porosity.". 2002, Icarus, 157, 155-172; Bottke et al. 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 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. However, few have been found. 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 … Methods. It is the seventh brightest asteroid with a mean opposition magnitude of +8.7. 2007), 1514 Ricouxa, and 1682 Karel in the … The Flora family asteroids … 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. It's also one of the brightest. Contents[show] General properties Large, prominent families contain several hundred recognized asteroids (and many more smaller objects which … [citation needed]. 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. [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. 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. This means that it is probably a piece from an asteroid collision that occurred roughly 200 million years ago. 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. en The results showed that for both asteroid families, generally the most precise version of the algorithm was the topocentric version. 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. In 1918, the Japanese astronomer K. Hirayama first recognized some non random concentrations of asteroid elements. [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 … Asteroid Flora. In the 1968 science-fiction film The Green Slime, an orbital perturbation propels the asteroid Flora into a collision course with Earth. This is a shape model of Flora computed using light curve inversion techniques. 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). Age: 500 million - 1 billion years. 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 Again, one of the largest families with more than 13.000 members, or about 3.5% of all main-belt asteroids.
