GL Gl 257B is an uncommon star. It lies about 26.2 light-years from Earth, sits in the constellation Pup, shines at apparent magnitude 11.7 and has spectral type M3.
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 257B in the constellation Pup. At apparent magnitude 11.7, a small backyard telescope will bring it into view.
Like any astronomical target, GL Gl 257B 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 257B scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Binary star, Cool red M-type star, Red dwarf 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.
