GL Gl 490B is an uncommon star. It lies about 59 light-years from Earth, sits in the constellation CVn, shines at apparent magnitude 13.2 and has spectral type dM4 e.
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 490B in the constellation CVn. At apparent magnitude 13.2, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, GL Gl 490B 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 490B scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Binary star, Cool red M-type star, Deep red star and Red dwarf — 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.
