IC 3557 NED01 is a rare galaxy. It lies about 1.15×10^9 light-years from Earth, sits in the constellation Com and shines at apparent magnitude 15.97.
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 3557 NED01 in the constellation Com. At apparent magnitude 15.97, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, IC 3557 NED01 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 3557 NED01 scores 37 points on Spacedle's rarity scale, which places it in the rare tier. Another 13 points would lift it into a rarer tier.
That score comes from 5 science badges — Galaxy, Outside our galaxy entirely, Elliptical galaxy, Ghostly low surface brightness 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.
