A diameter of 290+/-15 km separates large spherical asteroids from smaller non-spherical ones. Theoretical considerations, based on the assessment of the mean energy associated with the interparticle forces between each asteroidal atom and its relationship to the gravitational force present, also indicate that somewhere between diameters of 140 and 380 km (dependent on the composition of the asteroid) there exists a dividing line between spherical asteroids and non-spherical ones.
