GL Gl 171.2B is a rare star. It lies about 58.2 light-years from Earth, sits in the constellation Tau, shines at apparent magnitude 15.8 and has spectral type DC8.
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 171.2B in the constellation Tau. At apparent magnitude 15.8, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, GL Gl 171.2B 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 171.2B scores 40 points on Spacedle's rarity scale, which places it in the rare tier. Another 10 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Binary star, On the zodiac, White dwarf (a burnt-out core) 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.
