31 Cam is an uncommon variable star. It lies about 468.6 light-years from Earth, sits in the constellation Cam, shines at apparent magnitude 5.2 and has spectral type A2V.
Its spectrum reads A2V — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for 31 Cam in the constellation Cam. At apparent magnitude 5.2, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 31 Cam 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.
31 Cam 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, Never sets (northern circumpolar), White A-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.
