Definition

6 Hebe is a large asteroid residing in the inner main belt with a semimajor axis of approximately 2.425 AU. Its orbit is inclined by about 14.748 degree and has an eccentricity of 0.201. With these orbital parameters, it is situated near the 3:1 resonance with Jupiter and the v6 secular resonance. This proximity makes it likely for ejecta of Hebe, which can be caused by impacts of smaller asteroids, to come into near-earth regions by mediation of Jupiter or Saturn. Hebe is therefore suggested to be one of the main contributors for the terrestrial meteoroid flux of H chondrites and the IIE iron meteorites.

With its diameter of 185.18 km and a mass between 1.2 and 1.4 × 10^19 kg, it has a similar average density as Mars even though it is much smaller. Hebe has been classified to be of spectral class S(IV), of which it is a relatively atypical member because of its low spectral slope and UV color.

History

Hebe was discovered in 1847 by Karl Ludwig Hencke in...
