How do satellites track space debris in orbit?

Satellites use special tools to watch and follow space junk, just like you use your eyes to see toy cars zooming around a track.

Imagine it's nighttime, and all the toys are glowing. You can tell where each one is because they light up, that’s like how satellites work! They have cameras that take pictures of space, helping them spot space debris, which is just old parts from rockets or broken satellites floating around.

Some satellites also use a kind of super GPS. Just like your phone uses GPS to tell you where you are on the street, these satellites use it to know exactly where the space junk is moving, and how fast! This helps them predict when two pieces might bump into each other.

All these tools work together so that scientists can keep track of all the floating bits in space. It's like having a toy map that shows you where every car is, so no one crashes!
