8 Flora is a big, bright, main beltasteroid. 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.[6] It is the seventh brightest asteroid with a mean oppositionmagnitude of +8.7.[7] Flora can reach a magnitude of +7.9 at a favorable opposition near perihelion, such as will occur in mid November 2007.
The name Flora was proposed by John Herschel, from Flora, the Latin goddess of flowers and gardens, wife of Zephyrus (the personnification of the West wind), mother of Spring, and whose Greek equivalent is Chloris (who has her own asteroid, 410 Chloris).
Characteristics
Flora is the parent body of the Flora family of asteroids, and by far the biggest member, having about 80% of the total mass of this family. But Flora was almost certainly disrupted by the impact(s) that formed the family, and is probably an aggregate of most of the pieces.
Flora's spectrum indicates that its surface is made of a mixture of silicate rock (including pyroxene and olivine) and nickel-iron metal. Flora, and the whole Flora family generally, are good candidates for being the parent bodies of the L chondrite meteorites.[8] This meteorite type comprises about 38% of all meteorites impacting the Earth.
