HR 2800 is an epic variable star. It lies about 2,489.7 light-years from Earth, sits in the constellation CMa, shines at apparent magnitude 6 and has spectral type B3V.
Its spectrum reads B3V — 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 HR 2800 in the constellation CMa. At apparent magnitude 6, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 2800 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 2800 scores 55 points on Spacedle's rarity scale, which places it in the epic tier. Another 23 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Distant (over 1,000 light-years), Hot blue B-type star, Main-sequence star, Blue-white star, Intrinsically luminous (Mv < −2), Barely variable (under 0.05 mag) and Fades out of naked-eye view — 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.
