IC 3084 is an uncommon galaxy. It lies about 316,413,196.5 light-years from Earth, sits in the constellation Com and shines at apparent magnitude 15.65.
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 IC 3084 in the constellation Com. At apparent magnitude 15.65, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, IC 3084 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.
IC 3084 scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.
That score comes from 3 science badges — Galaxy, Outside our galaxy entirely and Faint fuzzy (mag > 13) — 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.
