The Cir is a rare variable star. It lies about 1,510 light-years from Earth, sits in the constellation Cir, shines at apparent magnitude 5.08 and has spectral type B4Vnp.
Its spectrum reads B4Vnp — 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 The Cir in the constellation Cir. At apparent magnitude 5.08, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, The Cir 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.
The Cir scores 49 points on Spacedle's rarity scale, which places it in the rare tier. Another 1 point 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, Hot blue B-type star, Main-sequence star, Blue-white star, Intrinsically luminous (Mv < −2) and Gently variable — 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.
