GL Gl 831A is a rare variable star. It lies about 27.1 light-years from Earth, sits in the constellation Cap, shines at apparent magnitude 11.96 and has spectral type M4e....
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 831A in the constellation Cap. At apparent magnitude 11.96, a small backyard telescope will bring it into view.
Like any astronomical target, GL Gl 831A 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 831A scores 46 points on Spacedle's rarity scale, which places it in the rare tier. Another 4 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Binary star, On the zodiac, Cool red M-type star, Deep red star, Red dwarf, Intrinsically feeble (Mv > +12) and Gently variable — 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.
