When we look up at the sky, we can see lots of stars and other objects that are very far away from us. Scientists give these objects special names so they can talk about them more easily.
First, they name the different constellations (groups of stars that form a pattern) after animals, mythical creatures, or other things they look like.
Then, they give each individual star a name based on the constellation it belongs to. For example, the brightest star in the Orion constellation is named Betelgeuse.
But scientists also give objects more scientific names so they can talk about them in a more specific way. For example, there's a star system called Alpha Centauri. It's made up of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.
The naming conventions for these objects can get pretty complicated, but they help scientists organize and study the many objects in the vast and fascinating universe.
