How Do Planets Stay in Orbit for So Long?

Planets stay in orbit for so long because they're dancing around the Sun in a never-ending game of balance.

Gravity is like an invisible string that pulls planets toward the Sun. Speed keeps them from crashing into it. It's like when you swing a ball on a string, if you let go, it flies off, but if you keep spinning it, it stays in a circle.

Imagine you're on a merry-go-round. If you hold on tight, you stay in your seat. But if you let go, you fly off! Planets are like that, they’re moving fast enough to not fall into the Sun, but not so fast that they escape into space.

This dance started a long time ago, when the solar system was born. Since then, planets have been going around the Sun without needing any help. It’s like having a perfect swing, you just keep moving, and it never stops.
