How Does the Solar System Stay in Order?

The Solar System stays in order because everything is balanced and moving together, just like a game of tag or a merry-go-round.

Imagine you're on a merry-go-round with your friends. You all hold hands, and when it spins, you all move around the center at the same time, no one gets left behind or flies off unless they let go. That’s kind of what happens in the Solar System!

How Balance Works

The Sun is like a big kid in the middle of the merry-go-round. It pulls on the planets with its gravity, which is like invisible string holding them in place.

Each planet keeps moving forward, just like you keep running around the merry-go-round, and because they're all going at the right speed, they don’t crash into each other or drift away.

Why They Don't Stop

Planets are always moving, and they have momentum, which is like when you’re on a swing, once you get going, you keep swinging even if no one pushes you. So the planets just keep going around the Sun forever, as long as nothing messes up their rhythm!
