What is the Relationship Between Latitude and Polaris?

Polaris Is also known as the North Star It is always in the northern nighttime sky. Is located above our Northern Celestial Pole (axis)

What would the altitude of Polaris be if you lived in Mt. Marcy NY? ***Polaris’ altitude (or height above the horizon) is EQUAL to an observer’s latitude *** What would the altitude of Polaris be if you lived in Mt. Marcy NY?

If you pass south of the equator, you can NO longer see Polaris As you move NORTH and your latitude increases, the altitude of Polaris also increases If you pass south of the equator, you can NO longer see Polaris As an observe travels east or west, the altitude of Polaris remains the same As an observe travels north or south,’ the altitude of Polaris changes b/c Earth has a curved surface

How can you find Polaris in the night sky? The pointer stars in the Big Dipper point north towards Polaris

In the NORTHERN hemisphere all the stars appear to rotate around Polaris
