GL Gl 255B is a common star. It lies about 140.9 light-years from Earth, sits in the constellation Pup, shines at apparent magnitude 7.1 and has spectral type F8 IV-V.
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 255B in the constellation Pup. At apparent magnitude 7.1, it is an easy target for binoculars.
Like any astronomical target, GL Gl 255B 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 255B scores 17 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Binary star, Yellow-white F-type star and Subgiant (leaving the main sequence) — 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.
