GL Gl 451B is a common star. It lies about 29.9 light-years from Earth, sits in the constellation UMa and shines at apparent magnitude 12.
It is a binary: two stars orbiting a shared centre of mass. More than half of all the 'stars' you can see are actually multiple systems.
Look for GL Gl 451B in the constellation UMa. At apparent magnitude 12, a small backyard telescope will bring it into view.
Like any astronomical target, GL Gl 451B is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
GL Gl 451B scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Binary star, Never sets (northern circumpolar) and Intrinsically feeble (Mv > +12) — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
