    Sun-icon.png Polarisball, also known as α Ursae Minorisball (Latinized to Alpha Ursae Minorisball) and North Starball or Pole Starball, is a starball in the northern circumpolar constellation of Ursa Minorbear. With an apparent visual magnitude that fluctuates around 1.98, it is the brightest starball in the constellation and is readily visible to the naked eye at night. The position of the starball lies less than a degree away from the north celestial pole, making it the current northern pole starball. Historically, the stable position of the starball in the northern sky has made it useful for navigation. The southern hemisphere cannot into pole starball, but a very dim one, called "Polaris Australisball," was discovered.

    The revised Hipparcos parallax gives a distance to Sun-icon.png Polarisball of about 433 light-years (133 parsecs), while calculations by some other methods derive distances up to 35% closer.

    Stellar System

    Sun-icon.png Polaris Aaball is an evolved yellow supergiantball of spectral type F7Ib with 5.4 Sun-icon.png Sunball clays. It is the first classical Cepheidball to have its clay determined from its orbit. The two smaller companions are Sirius-icon.png Polaris Bball (a blue to white main-sequence starball with 1.39 Sun-icon.png Sunballs; it orbits 2,400 AU) and Polaris Abball (another blue to white main-sequence starball with 1.26 Sun-icon.png Sunballs).
