Polaris is the brightest star in the constellation Ursa Minor. It is very close to the north celestial pole, making it the current northern pole star. It is a multiple star, consisting of the main star α UMi Aa, two smaller companions, α UMi B and α UMi Ab, and two distant components α UMi C and α UMi D. α UMi B was discovered in 1780 by William Herschel. Many recent papers calculate the distance to Polaris at about 434 light-years. Some suggest it may be 30% closer which, if correct, is especially notable because Polaris is the closest Cepheid variable to Earth so its physical parameters are of critical importance to the whole astronomical distance scale.
