How Does NASA's plan to save Earth from a giant asteroid Work?

NASA has a clever plan to gently push a giant asteroid off its path so it won’t crash into Earth.

Imagine you're playing tag on a big field, and the giant asteroid is like a very fast friend chasing you. NASA wants to give that friend a little nudge so they end up running in a different direction, not toward you anymore!

NASA uses a spacecraft, kind of like a tiny remote-controlled car. This car zooms up close to the asteroid and then pushes it gently by bumping into it. It's like giving the asteroid a light tap on its side, which makes it slowly change direction over time.

This works because even a little push can make a big difference when you're moving super fast, just like how a small kick from your friend can send a soccer ball flying across the field!

It might take years for the asteroid to move enough so that it misses Earth, but NASA has plenty of time to work on it. They can check in on the asteroid regularly and give it more taps if needed, like giving your friend another kick to help them run even farther away!
