ELI5: Explain Like I'm 5

Barton (crater)

So, imagine you're playing with some clay and you make a big circle. That's like what a crater is on a really big scale! But instead of being made of clay, it's made on the moon and it's really, really big.

The Barton Crater is a big circle on the moon that was made a long time ago when a big rock from space crashed into it. It's named after a big important scientist named Ralph Barton who studied rocks and space.

Scientists like to study the Barton Crater because it tells them a lot about what the moon is made of and how it's changed over time. They use special cameras and tools to look at the rocks and dirt inside the crater to learn more about it. It's kind of like how you might look inside a toy to figure out how it works!
