HR 1040 is an epic variable star. It lies about 2,508.9 light-years from Earth, sits in the constellation Cam, shines at apparent magnitude 4.55 and has spectral type A0Ia SB:.
Its spectrum reads A0Ia SB: — 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 HR 1040 in the constellation Cam. At apparent magnitude 4.55, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 1040 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.
HR 1040 scores 61 points on Spacedle's rarity scale, which places it in the epic tier. Another 17 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Distant (over 1,000 light-years), Naked-eye visible, Never sets (northern circumpolar), White A-type star, Supergiant, Intrinsically luminous (Mv < −2) and Barely variable (under 0.05 mag) — 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.
