Planets stay in orbit because they are constantly being pulled by gravity, but they're also moving forward, like a ball attached to a string that's being swung around. If the pull was too strong, planets would crash into the sun; if it wasn't strong enough, they'd float away into space. It's all about balance. This is why we keep seeing the same patterns in our solar system.
Examples
- Earth’s orbit around the sun works similarly to how a ball thrown in the air follows a curved path before coming back down.
- Mars’ elliptical orbit shows that not all orbits are perfect circles, just like how a pendulum swings more slowly when it's longer.
