What Happens to Old Satellites When They Die?

When old satellites stop working, they just float around in space, but sometimes they crash back down to Earth.

Imagine your toy airplane: when it runs out of batteries, it stops flying. It might just sit there on the floor, or maybe it crashes into a wall or falls off the table. Old satellites are like that toy airplane, they stop working and hang out in space.

Sometimes, old satellites burn up as they come back to Earth, like when you light a match and it goes whoosh! and disappears. Other times, pieces of them might actually land on the ground, just like if your toy airplane landed on the floor after crashing.

Some satellites are sent back down to Earth on purpose, kind of like how you might throw a ball up in the air and catch it again. These ones are called "controlled reentries." They come back smoothly, like a slow-motion crash landing.

But other old satellites just drift around until gravity pulls them back, sort of like when your toy airplane falls off the table because it ran out of batteries. When old satellites stop working, they just float around in space, but sometimes they crash back down to Earth.
