Astronomy:Juno clump
From HandWiki
The Juno clump is a probable main-belt asteroid family that share similar orbital elements to 3 Juno.
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
| a | e | i | |
|---|---|---|---|
| min | 2.64 AU | 0.238 | 11.8° |
| max | 2.68 AU | 0.274 | 14.6° |
