NGC 1203B is a common galaxy. It sits in the constellation Eri and shines at apparent magnitude 16.
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 NGC 1203B in the constellation Eri. At apparent magnitude 16, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, NGC 1203B 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.
NGC 1203B scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point would lift it into a rarer tier.
That score comes from 3 science badges — Galaxy, Elliptical galaxy 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.
