Mirzam is an epic variable star. It lies about 492.7 light-years from Earth, sits in the constellation CMa, shines at apparent magnitude 1.98 and has spectral type B1II/III.
Its spectrum reads B1II/III — 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 Mirzam in the constellation CMa. At apparent magnitude 1.98, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Mirzam 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.
Mirzam scores 59 points on Spacedle's rarity scale, which places it in the epic tier. Another 19 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Naked-eye visible, Has a proper name, Hot blue B-type star, Bright giant, Blue-white star, 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.
