Zet1Sco is an epic variable star. It lies about 2,568.2 light-years from Earth, sits in the constellation Sco, shines at apparent magnitude 4.7 and has spectral type B1Iae.
Its spectrum reads B1Iae — 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 Zet1Sco in the constellation Sco. At apparent magnitude 4.7, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Zet1Sco 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.
Zet1Sco scores 63 points on Spacedle's rarity scale, which places it in the epic tier. Another 15 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, On the zodiac, Hot blue B-type star, Supergiant, 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.
