What are groups of stars?

Groups of stars are teams of stars that hang out together in the sky.

Imagine you're playing tag at the park, some kids run off by themselves, but others stick together to make it harder for the person chasing them. That’s like how groups of stars work: they’re all moving together in space, making a cool pattern we can see from Earth.

Some groups of stars are families that have been together for a really long time, so long, in fact, that they’ve become kind of stuck to each other. These families are called star clusters, and you can think of them like a group of kids who all live on the same street and ride bikes together every day.

Other groups of stars aren’t as close, but still hang out sometimes, just like friends who meet up once in a while for a game of soccer. These are called constellations, and they're like stories told by the stars, helping us remember which ones are part of the same group.

So next time you look at the night sky, try to find your favorite star cluster or constellation, it's like finding your favorite group of friends in the sky!
