Is Polaris hotter that the sun?
Polaris, also known as the North Star, is actually cooler than the Sun. It has a surface temperature of about 6,000 K, while the Sun's surface temperature is around 5,500 K. However, Polaris is a more luminous star than the Sun, emitting significantly more energy due to its larger size and greater brightness. Thus, while it is hotter in terms of luminosity, its surface temperature is lower than that of the Sun.
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.
