Altair is the major star in the constellation Aquilla which is the eagle. It's part of the "Summer Triangle" (summer constellations in the northern hemisphere) which is the constellations Aquilla, Lyra (harp), and Cygnus (swan).
Altair does NOT mean "son of none." Whoever said this is most likely basing it off the character Altair ibn La-Ahad from the video game, Assassin's Creed. The latter part of the character's name means "son of none." Altair means either "the bird," "the flying one," or a variation of the two.
