How is a Polaris star formed?

A Polaris star, like any other star, forms from a dense region of gas and dust in a molecular cloud. As gravity pulls the material together, it begins to collapse and heat up, eventually forming a protostar. Once the core temperature becomes high enough for nuclear fusion to ignite, hydrogen atoms fuse into helium, marking the birth of the star. Polaris, specifically, is a supergiant star in the late stages of its life, having evolved from a main-sequence star.
