What is the north star made up of?

The North Star, also known as Polaris, is primarily composed of hydrogen and helium, like most stars. It is a supergiant star, specifically a Cepheid variable, which means it has a significant mass and size compared to our Sun. Polaris is located about 433 light-years away from Earth and is part of the constellation Ursa Minor. Its brightness and position make it a key navigational star in the northern sky.
