Why Are Planets Round? | COLOSSAL QUESTIONS?

Planets are round because everything pulls together until it forms a ball, just like when you squeeze playdough until it's smooth and round.

Gravity is what makes this happen. It’s the invisible force that pulls things toward each other, like when you drop a toy on the floor, gravity brings it back down.

When a planet starts to form, tiny pieces of rock and ice come together. As more stuff adds up, gravity gets stronger, pulling everything in. Think about stacking blocks, the more blocks you add, the heavier the pile becomes, and the harder it is to keep them all straight.

Eventually, gravity pulls all those bits into one smooth shape, a ball. That’s why planets end up round, just like how a marble rolls until it’s perfectly rounded.

If something doesn’t have enough stuff pulling together, it might stay lumpy or irregular, like a potato instead of a marble. But big things like planets get pulled into balls because gravity is strong enough to smooth everything out.
