Coma Pinwheel is a rare galaxy. It lies about 112,250,417.1 light-years from Earth, sits in the constellation Com and shines at apparent magnitude 9.84.
A galaxy: a gravitationally bound city of stars, gas and dark matter, turning so slowly that a single rotation takes hundreds of millions of years.
Look for Coma Pinwheel in the constellation Com. At apparent magnitude 9.84, a small backyard telescope will bring it into view.
Like any astronomical target, Coma Pinwheel 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.
Coma Pinwheel scores 45 points on Spacedle's rarity scale, which places it in the rare tier. Another 5 points would lift it into a rarer tier.
That score comes from 5 science badges — Galaxy, Outside our galaxy entirely, Messier object, Has a proper name and Spiral galaxy — 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.
