Polaris from the X-Men comics
Polaris (po-LAR-iss or po-LAIR-iss - to each his own) is known as the North Star in the night sky, the Lodestar, traditionally also known as the "guiding star" or "pole star." The name means "of the [north] pole" in Latin, while the Greek name for it meant "dog's tail" in mistaken reference to the constellation Ursa Minor in which Polaris resides. Many believe it is the brightest star in the sky, but it is actually the 45th brightest. It does, however, play an important role in navigation because it remains nearly motionless.
Polaris has been used in some fiction, although nothing very recognizable. It was used three times in the DC Comics universe for the fictional Polaris star system or Polaris Galaxy, on a Super Mario Galaxy character, in "Teenage Mutant Ninja Turtles," and for three computer games. Polaris aka Lorna Dane was an X-Men character with the power of magnetism (fun fact: Magneto is her dad, Scarlett Witch and Quicksilver are her siblings).
Because this name has only been used for the star and not typically on people, it can be considered unisex. Nicknames on a girl might include Pola, Polly or Priss, while boys could be Poe or Polo.
Polaris was recorded just once - in 2010 on 5 baby girls. That's it, although nothing is recorded under 5 births so there are likely more, and that's exactly what White Pages says when listing 30 in the U.S.
