What are inclination of planetary orbits?

Imagine you're spinning around on your favorite merry-go-round, and instead of going straight up and down, you tilt a little bit as you go, that’s inclination in the world of planets!

Planets don’t all orbit their suns in perfectly flat circles. Some are like swings on a swing set, they move in paths that are tilted a little compared to each other. This tilt is called inclination.

Think about your favorite swing: if you push it straight forward, it moves in a mostly flat path. But if you give it a slight twist, the swing moves up and down and side to side, like going around the sun in a slightly slanted circle. That’s what happens with planets!

Some planets have very little tilt, they’re like swings that go almost straight forward. Others are more tilted, like when you give your swing a big twist and it goes up, down, and even sideways! This tilt affects how the planet experiences seasons and how it moves through space.

So next time you're on a swing, remember: you're acting just like a planet in space, giving its orbit a little inclination!
