Polaris Aa is an evolved yellow supergiant of spectral type F7Ib with 5.4 solar masses ( M☉ ). It is the first classical Cepheid to have a mass determined from its orbit. The two smaller companions are Polaris B, a 1.39 M☉ F3 main-sequence star orbiting at a distance of 2,400 astronomical units (AU), [17] and Polaris Ab (or P), a very close ...
A pole star is a visible star that is approximately aligned with the axis of rotation of an astronomical body; that is, a star whose apparent position is close to one of the celestial poles. On Earth, a pole star would lie directly overhead when viewed from the North or the South Pole .
Fifty-seven navigational stars and additionally the star Polaris are given a special status in the field of celestial navigation.
