Polaris, also known as the North Star, is a supergiant star in the constellation Ursa Minor. It has evolved through several stages: it began as a main-sequence star, fusing hydrogen into helium. As it exhausted its hydrogen fuel, it expanded into a red giant before shedding its outer layers, leading to its current state as a yellow supergiant. Eventually, Polaris will end its life in a supernova explosion, leaving behind a neutron star or black hole.
