9 Aur is an uncommon variable star. It lies about 85.7 light-years from Earth, sits in the constellation Aur, shines at apparent magnitude 4.98 and has spectral type F0V.
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 9 Aur in the constellation Aur. At apparent magnitude 4.98, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 9 Aur 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.
9 Aur 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 7 science badges — Variable star, Naked-eye visible, Binary star, Yellow-white F-type star, Main-sequence star, Gently variable and A named variable 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.
