What is Orbital clearance?

Orbital clearance is like making sure no one else is playing on your favorite slide at the playground.

Imagine you and your friends are all sliding down the same big slide at the park. If everyone tries to use it at once, it gets crowded and confusing, sometimes even a little crashy! That’s orbital clearance in space: it means that a planet or object has cleared its orbit of other things, like smaller rocks or other planets, so it can move smoothly without getting bumped around.

Think of it as sweeping your room before bedtime. If you leave all your toys and books scattered around, it’s hard to find your favorite blanket. But when you sweep everything up, that's orbital clearance! A planet with good orbital clearance has no distractions, just a clear path around the Sun.

When something has cleared its orbit, we know it's been doing this for a long time, maybe even billions of years! That means it’s like the big kid on the playground who’s been sliding down the same slide without anyone getting in their way.
