GL Gl 40B is a common star. It lies about 49.6 light-years from Earth, sits in the constellation Cet, shines at apparent magnitude 17.3 and has spectral type m.
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 40B in the constellation Cet. At apparent magnitude 17.3, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, GL Gl 40B 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 40B scores 15 points on Spacedle's rarity scale, which places it in the common tier. Another 7 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, Binary star 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.
