How to find Ursa Major _ How to find Polaris in Ursa Major

What's the difference between Ursa major and Ursa minor?

The whole northern sky is a dark star, and only Polaris and Big Dipper are brighter, so these two constellations are very easy to identify. Ursa major is brighter than Ursa minor, but the Polaris on Ursa minor's tail is the only second-class star in the northern sky, and it is also the only star in the whole starry sky that has a relatively constant position and does not rotate. Polaris can be found at the connection point five times the opening of Cassiopeia W. The Big Dipper in Ursa Major will revolve around Polaris, which is above the horizon all night.

After you find Polaris in Ursa major, you can always find Ursa minor, because Polaris is also the last star at the tail of Ursa minor. Conversely, you can easily find Ursa minor.
