In your reflection, you thought about how you navigate or find your way around our planet.

Astronomers have been around for many years and they navigate by the stars. Even some animals navigate by the stars. The indigo bunting is one animal that uses the stars for guidance as it migrates at night.

There are 57 stars that are used for navigation because they are easy to find and brighter than their surrounding stars. Polaris, the North Star is one star that is commonly used to navigate. Our sun is another star that is often used in navigation.
