GL Gl 815A is a rare variable star. It lies about 49.9 light-years from Earth, sits in the constellation Cyg, shines at apparent magnitude 10.12 and has spectral type M3Ve.
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 815A in the constellation Cyg. At apparent magnitude 10.12, a small backyard telescope will bring it into view.
Like any astronomical target, GL Gl 815A 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 815A scores 39 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Binary star, Cool red M-type star, Main-sequence star, Deep red star, Red dwarf, Gently variable and A named variable star — 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.
