Why is it the earth is round?
Why is it not square or triangle
The earths own gravity pulls in into a round shape. Like when you squeeze snow evenly on all sides it turns into a snowball. There are some moons and asteroids that don't have enough gravity to become round so they look more like potatoes.
The points on your cubical planet (or triangular) would be tall mountains that would be crushed under their own weight and flattened.
Gravity tends to pull matter into spherical shapes. The strength of the materials resist this pulling. If a body is large enough (a planet), then gravity becomes strong enough to overcome the properties of the materials.
Earth is not a perfect sphere, though, because of the gravity of the Moon and Sun. Earth is considered to be an oblate spheroid.

I ask because this was brought to my attention...The moon does not spin, as it simply orbits around the Earth. There is nothing pulling on its axis to cause it to spin. So say we did not have a moon, would the Earth...
