GL GJ 3899 is an uncommon star. It lies about 64 light-years from Earth, sits in the constellation Ser, shines at apparent magnitude 14.02 and has spectral type DA wk.
Its spectrum reads DA wk — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.
Look for GL GJ 3899 in the constellation Ser. At apparent magnitude 14.02, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, GL GJ 3899 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 3899 scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, 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.
