Space junk is like toys that don't come back, they just keep floating around and can hit other toys or even people.
Imagine you're playing in a big room with your friends, and everyone throws their toys at each other. Now imagine no one picks up the toys after they’re thrown. Soon, the room gets really messy, and the flying toys might even hurt someone. That's what's happening in space, space junk is all those old toys (like broken satellites or parts from rockets) that are still floating around.
Why it’s getting worse
Every time a rocket goes up or a satellite breaks, more space junk gets added to the mix. It’s like if every time you played, someone threw in ten new toys, soon the room would be full of flying stuff! And because there's so much junk now, it can crash into other satellites or even spaceships, making them break.
Sometimes, this crashing junk creates more junk, just like when a toy breaks apart and makes smaller pieces that fly everywhere. That’s why scientists are worried, if we don’t clean up space, soon it might be impossible to use space for fun or work anymore!

Examples
- Space debris is like litter in the sky that could hit astronauts or spaceships.
- We can't see all the tiny bits of space junk floating around Earth.
