GL GJ 9490A is a common star. It lies about 82.2 light-years from Earth, sits in the constellation Boo, shines at apparent magnitude 10.08 and has spectral type M0.
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 GJ 9490A in the constellation Boo. At apparent magnitude 10.08, a small backyard telescope will bring it into view.
Like any astronomical target, GL GJ 9490A 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 9490A scores 20 points on Spacedle's rarity scale, which places it in the common tier. Another 2 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Binary star, Cool red M-type 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.
