Astronomy:Juno clump

From HandWiki

The Juno clump is a probable main-belt asteroid family that share similar orbital elements to 3 Juno.

Location and structure of the Juno clump.

3 Juno is a large asteroid with a mean diameter of about 235 km, but the remaining bodies are all small. (32326) 2000 QO62, the brightest of those clearly in the visible clump would have a diameter of about 6 km, given the same albedo as 3 Juno. This indicates that it is probably a so-called cratering family composed of ejecta from impacts on 3 Juno.

The HCM analysis by (Zappalà 1995) determined several likely core members, whose proper elements lie in the approximate ranges

ap ep ip
min 2.64 AU 0.226 13.3°
max 2.68 AU 0.240 13.9°

At the present epoch, the range of osculating orbital elements of these core members is

min 2.64 AU 0.238 11.8°
max 2.68 AU 0.274 14.6°
