Chamukuy is a rare variable star. It lies about 150.4 light-years from Earth, sits in the constellation Tau, shines at apparent magnitude 3.4 and has spectral type A7III.
Its spectrum reads A7III — 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 Chamukuy in the constellation Tau. At apparent magnitude 3.4, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Chamukuy 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.
Chamukuy scores 40 points on Spacedle's rarity scale, which places it in the rare tier. Another 10 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Naked-eye visible, Has a proper name, On the zodiac, White A-type star, Giant star, Barely variable (under 0.05 mag) and A named variable star — 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.
