Coathanger Asterism is an epic cluster. It sits in the constellation Vul and shines at apparent magnitude 3.6.
A stellar association: a sprawling family of hot young stars that shared a birthplace but were never gravitationally bound to each other.
Look for Coathanger Asterism in the constellation Vul. At apparent magnitude 3.6, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Coathanger Asterism 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.
Coathanger Asterism scores 53 points on Spacedle's rarity scale, which places it in the epic tier. Another 25 points would lift it into a rarer tier.
That score comes from 6 science badges — Star cluster, Bright deep-sky object, Has a proper name, Loose stellar association, Bigger on the sky than the full Moon and Bright enough for the unaided eye — 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.
