846 Lipperta is a Themistian asteroid.

Based on lightcurve studies, Lipperta has a rotation period of 1641 hours, but this figure is based on less than full coverage, so that the period may be wrong by 30 percent or so.[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 uniform albedo.[2]
