What are geostationary orbits?

A geostationary orbit is like having a toy that stays right above you while you spin around on a merry-go-round.

Imagine you're sitting on a merry-go-round and spinning really fast. If you had a friend holding a ball just the right distance away, the ball would look like it's not moving at all, even though both of you are spinning. That’s what happens with satellites in a geostationary orbit: they're going around Earth at the same speed that Earth spins, so they always stay above the same spot.

Earth spins once every 24 hours. A satellite in a geostationary orbit goes around Earth once every 24 hours too, but much higher up, about 36,000 kilometers away! That means it stays right above the same city or country all day long.

Because they stay in one place, geostationary satellites are perfect for things like weather reports and TV signals. They can watch the whole sky without moving, just like your friend holding that ball still while you spin!
