Its apparent magnitude is about 2, but it's slightly variable. Usually it's given as 1.97v (where v means variable).
This is the order from smallest stars to the biggest stars: Alpha Centauri, Procyon, Vega, Pollux, Polaris, and Deneb. These are the size(diameter) of them; though the size of the stars are not 100% accurate so they are likely to be predicted. Alpha Centauri is 1,527,000 Procyon is 2,652,000 Vega is 3,827,000 Pollux is 11,617,000 Polaris is 44,217,000 and Deneb is 203,000,000
supergiant
The surface temperature of the Pollux star is 4,500 K
Pollux is a red giant star and is estimated to be around 8.8 times the size of our Sun. Its radius is approximately 72 million kilometers.
Polaris is actually a system of three stars, all of them larger than the sun. They range in size from 1.26 to 5.4 times the diameter of the sun. Polaris only appears smaller than the sun because it is several million times farther away.
Polaris A is a white supergiant.
Polaris by far. It has a diameter of 75 times the diameter of the Sun. Alpha Cen B has a diameter of 1.7 solar diameters.
the polaris is much larger than sun because polaris is a super giant star while sun is only a dwarf
Pollux is an orange giant star in the constellation of Gemini.It is about 8 times larger than our Sun, so about 512 Suns would fit in Pollux
Polaris has a radius around 30 times that of our own sun.
The main star of the Polaris System has a mass which is 4.5 times that of the sun.
