Detailed explanation-1: -For these igneous planetesimals, the diameter needed to overcome rigid body forces and become round is about 620 miles (1, 000km). The main belt asteroid Vesta is 326 miles (525km) in diameter.
Detailed explanation-2: -Asteroids are splitters of bigger things and so have NO liquid inner things and so they can‘t transform into a sphere.
Detailed explanation-3: -The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars.
Detailed explanation-4: -But to answer it simply, the reason big astronomical objects are spherical (or nearly spherical) is because they’re massive enough that their gravitational pull can overcome the strength of the material they’re made from.
