Like a Swing Set
Think about how you swing on a swing set: you push off, go up high, then come back down again. That’s what happens with orbits: a planet or moon is like you swinging, it keeps going around the thing it's orbiting because of gravity, which acts like an invisible hand pulling it back every time it goes too far.
The Push and Pull
When Earth was born, it got a big push from the early solar system. That push kept it moving forward, but gravity from the Sun pulled it in, so instead of flying off into space or crashing into the Sun, it went around and around like a space swing.
So orbits are just like a balance between how fast something is moving and how strong the pull (gravity) is from what it's going around. That’s why we have years, seasons, and even moon phases, all because of this fun, spinning dance in space!
