Imagine the universe is like a giant playground, with many little rocks called minor planets playing in different groups. Just like how you might have friends you like to play with and stay close to on the playground, minor planets also like being in groups with similar characteristics.
There are many different types of minor planet groups, such as asteroids or Kuiper Belt objects, and they each have their own unique qualities that make them special. For example, some minor planets might be really small while others are much bigger, and some might be closer to the sun while others are further away.
By studying these minor planet groups, scientists can learn more about the history and formation of our solar system. They can also use this information to better understand how to protect Earth from potentially dangerous collisions with these minor planets.
So just like how you have your own group of friends on the playground, minor planets also have their own groups that they like to play and hang out with in the big universe playground!
