Asteroids are so small that gravity is negligible. She is not able to give them the shape of a ball, which gives the planets and their large companions, crushing and ramming their substance. An important role is played by the phenomenon of fluidity. The high mountains on Earth at the bottom “sprawl”, because the strength of the rocks is insufficient to withstand loads of many tons per 1 cm3, and the stone, without crushing, without breaking, flows, although very slowly.
On asteroids with a diameter of up to 300-400 km, due to their low weight, such a phenomenon of fluidity is completely absent, while on the largest asteroids it occurs extremely slowly, and even then only Continue reading
