How Do Planets Stay in Their Orbits?

Imagine you're on a swing, when you push off, you go up and come back down. Planets are like swings that never stop moving! They’re pulled by the sun’s gravity, but they also keep moving sideways so they don’t fall straight in. It's like being on a giant, never-ending swing ride.

Gravity Pulls, Motion Keeps Them Going

The sun pulls planets toward it with gravity, just like how Earth pulls you down when you jump. But the planets are also moving fast enough sideways that they don’t fall straight in, instead, they keep looping around and around.

Examples

A ball tied to a string keeps spinning around your head, if you let go, it would fly off into space or fall straight down.
Like when you ride a merry-go-round, you're being pulled inward by the center but keep moving forward as you spin.
Imagine a dog chasing its tail, it's always running in circles without falling in.
