What are satellite galaxies?

A satellite galaxy is like a little friend that goes around a bigger galaxy, just like how Earth goes around the Sun.

Imagine you have a big toy ball (like your favorite planet) and some smaller ones (like tiny marbles). The small marbles zoom around the big one because it’s stronger, this is kind of like what happens in space!

Satellite galaxies are smaller galaxies that orbit around bigger ones. Just like how moons go around planets, these little galaxies go around bigger ones.

Our own Milky Way galaxy, which we live in, has some satellite galaxies too! One of them is called the Large Magellanic Cloud, it looks like a fuzzy cloud in the night sky, and it dances around our galaxy.

These satellite galaxies aren’t just floating around randomly; they’re pulled by gravity, the same force that makes you stay on Earth instead of floating off into space. So even though they look tiny from far away, they're still part of a big cosmic dance!
