Why aren't small asteroids spherical in shape?
A)The strength of gravity on small asteroids is less than the strength of the rock.
B)Small asteroids have odd shapes because they were all chipped off larger objects.
C)Large asteroids were once molten and therefore became spherical,but small asteroids were never molten.
D)Large asteroids became spherical because many small collisions chipped off pieces until only a sphere was left;this did not occur with small asteroids.

The strength of gravity on small asteroids is not strong enough to overcome the material strength of the rock, preventing them from forming into spherical shapes. Gravity on larger bodies is strong enough to shape them into spheres by pulling the material inward, but on small asteroids, the gravitational force is too weak to alter their irregular shapes.
