Vesta family

The cratering family is located in the inner asteroid belt in the vicinity of its namesake and principal body, 4 Vesta.

The brightest of these, 1929 Kollaa and 2045 Peking, have an absolute magnitude of 12.2, which would give them a radius of about 7.5 km assuming the same high albedo as 4 Vesta.

A HCM numerical analysis (by Zappala 1995) determined a large group of 'core' family members, whose proper orbital elements lie in the approximate ranges: This gives the approximate boundaries of the family.

A search of a recent proper-element database (AstDys) for 96,944 minor planets in 2005 yielded 6,051 objects (about 6% of the total) lying within the Vesta-family region as per the first table above.

These include 306 Unitas, 442 Eichsfeldia, 1697 Koskenniemi, 1781 Van Biesbroeck, 2024 McLaughlin, 2029 Binomi, 2086 Newell, 2346 Lilio, and others.
