How do expect its shape to be a disk?

We know everything rotates the sun while spinning. The moon rotates around earth. This is in respect to their size and gravitational pull. Everything is going in circles. Wouldn't it make sense that the shapes of these massive rocks be spherical?

The moon on the other hand is an anomaly. I do believe it's spherical but don't believe it formed here naturally. It's size and lock rotation it has with earth. The perfect position it has relative to eclipses with the sun is near perfection. The fact that the same side faces the earth. It rings hollow when it was struck. The craters have the same depth no matter how big the meteors hit.

That thing is perfect for surveillance ;)
