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

Question

Quizplus · Accepted Answer

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 can pull the material into a spherical shape, but on smaller asteroids, the gravitational force is too weak to alter the shape significantly.
