First of all, the answer has something to do with how gravity works and the creation of our solar system. Our solar system was created like a lot of other solar systems from a nebula. A nebula is something that can begin a star’s birth. A nebula is a cloud of gases and dust. The nebula spins very fast under the gravity that keeps getting bigger and the gas goes under nuclear fusion which causes a star to be born. After the birth of a star, there are two powers of gravity that fight over the left over gases and dust from the star’s birth. The two powers of gravity squish the gases and dust together. Then, larger element will collide together to make the beginnings of rocky planets.  Next, matter pulls in, to smooth out the rough edges of the planets.

Now you know why planets are round because of nebulas, gravity, and the formation of our solar system.
