GL GJ 3902 is a trash star. It lies about 72.5 light-years from Earth, sits in the constellation UMi, shines at apparent magnitude 13.44 and has spectral type m.
Its spectrum reads m — 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 3902 in the constellation UMi. At apparent magnitude 13.44, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, GL GJ 3902 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 3902 scores 7 points on Spacedle's rarity scale, which places it in the trash tier. Another 8 points would lift it into a rarer tier.
That score comes from 2 science badges — Star and Never sets (northern circumpolar) — 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.
