Polaris is a trinary system of three stars. Polaris A, the primary, is an F7 supergiant star and it's temperature is 6,000 K to 7,000 K(the temperature varies because the star is a Cepheid variable). Polaris B is a F3V main sequence star and has a stable temperature at 6,400 K. Polaris Ab is an F7V dwarf with a stable temperature of around 6,400 K.
