Polaris, also known as the North Star, is significantly larger than Proxima Centauri b, which is an exoplanet orbiting the red dwarf star Proxima Centauri. Polaris is a supergiant star with a radius about 30 times that of the Sun, while Proxima Centauri is a small, low-mass star, about 14% the mass of the Sun. In terms of size, Polaris is vastly larger than Proxima Centauri b's host star.
Pollux is larger than Polaris. Pollux, a binary star in the constellation Gemini, has a radius about 8.5 times that of the Sun, while Polaris, the North Star in the constellation Ursa Minor, has a radius approximately 2.5 times that of the Sun. Thus, Pollux is significantly larger in size compared to Polaris.
Its apparent magnitude is about 2, but it's slightly variable. Usually it's given as 1.97v (where v means variable).
The name of the north star is Polaris. As the brightest star in the constellation of Ursa Minor it is also called alpha Ursae Minoris. It is actually a multiple star comprised of Polaris Aa, Polaris Ab and Polaris B.
The common name for Polaris, the North Star, is simply "Polaris."
