GL GJ 3991 is a rare star. It lies about 24.3 light-years from Earth, sits in the constellation Her, shines at apparent magnitude 11.77 and has spectral type M3.
Its spectrum reads M3 — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.
Look for GL GJ 3991 in the constellation Her. At apparent magnitude 11.77, a small backyard telescope will bring it into view.
Like any astronomical target, GL GJ 3991 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 GJ 3991 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 6 science badges — Star, Nearby (<25 ly), Cool red M-type star, Deep red 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.
