846 Lipperta is a slowly rotatingThemistian asteroid located in theasteroid belt at a distance of 3.1 AU. It has a slow rotation period of 1641 hours making itone of the slowest rotating objects in thesolar system discovered.[3]
Based onlightcurve studies, Lipperta has arotation period of 1641 hours, but this figure is based on less than full coverage, so that the period may be wrong by 30 percent.[1] The lack of variation in brightness could be caused by (a) very slow rotation, (b) near pole-on viewing aspect, or (c) a spherical body with uniformalbedo.[2]
It has been claimed that 846 Lipperta may show comet-like activity but this claim is unconfirmed.[3]
