Imagine you're walking through a big park with lots of different animals like lions, tigers, and bears. Well, scientists have found out that there are also lots of big rocks called asteroids flying through space. They have different shapes and sizes just like the animals in the park. So scientists decided to call this group of asteroids an "asteroid zoo."
Just like a zookeeper takes care of the animals in the park, scientists like to study and learn about the asteroids in the asteroid zoo. They use really cool machines and tools to take pictures and measurements of the asteroids so they can understand how they move and what they're made of. This helps them figure out if any of them might be dangerous to Earth.
But don't worry, just like you're safe from the lions, tigers, and bears in the park, scientists know how to keep us safe from any asteroids that might be headed our way. So we can all enjoy looking at the fascinating asteroid zoo from a safe distance.
