GL Gl 153A is a common star. It lies about 56.5 light-years from Earth, sits in the constellation Cam, shines at apparent magnitude 9.17 and has spectral type K0.
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 153A in the constellation Cam. At apparent magnitude 9.17, a small backyard telescope will bring it into view.
Like any astronomical target, GL Gl 153A 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 153A scores 16 points on Spacedle's rarity scale, which places it in the common tier. Another 6 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Binary star, Never sets (northern circumpolar) and Orange K-type star — 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.
