Why Do We Use ‘Stars’ to Navigate in the Ocean?

Stars are like giant signs in the sky. Imagine you're on a boat and it's dark, you can't see land, but you can see the stars above you. Sailors used to know where they were by looking at certain stars, just like how we use maps today. It’s kind of like having a special map that only works at night.

When sailors look up, they see constellations, groups of stars that stay in the same place every night. They can tell their direction or even where they are by knowing which stars appear when and how far away they seem to be.
