Most asteroids are irregularly shaped, though a few are nearly spherical, and they are often pitted or cratered. As they revolve around the Sun in elliptical orbits, the asteroids also rotate, sometimes quite erratically, tumbling as they go.

Webb1 apr. 1989 · As a mediate shape model between the ellipsoid and convex model, Cellinoid shape model was introduced first by Cellino et al. (1989), which consists of eight octants from ellipsoids. With asymmetric shape, Cellinoid shape model of having three more parameters than triaxial ellipsoid model, can simulate the shapes of real asteroids better.
WebbThe rotation periods and shapes of asteroids are determined primarily by monitoring their changing brightness on timescales of minutes to days.
