42 Cam is a rare star. It lies about 924 light-years from Earth, sits in the constellation Cam, shines at apparent magnitude 5.14 and has spectral type B4IV.
Its spectrum reads B4IV — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.
Look for 42 Cam in the constellation Cam. At apparent magnitude 5.14, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 42 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.
42 Cam scores 41 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.
That score comes from 7 science badges — Star, Naked-eye visible, Never sets (northern circumpolar), Hot blue B-type star, Subgiant (leaving the main sequence), Blue-white star and Intrinsically luminous (Mv < −2) — 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.
