The Juno clump is a probable main-belt

asteroid family An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. An a ...

is a large asteroid with a mean diameter of about 235 km, but the remaining bodies are all small. , the brightest of those clearly in the visible clump would have a diameter of about 6 km, given the same albedo as

. 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 At the present epoch, the range of osculating

orbital elements Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems using a Kepler orbit. There are many different ways to mathematically describe the same ...
