Sextans A is an epic galaxy. It lies about 15,099,888.1 light-years from Earth, sits in the constellation Sex and shines at apparent magnitude 11.77.
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 Sextans A in the constellation Sex. At apparent magnitude 11.77, a small backyard telescope will bring it into view.
Like any astronomical target, Sextans A 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.
Sextans A scores 50 points on Spacedle's rarity scale, which places it in the epic tier. Another 28 points would lift it into a rarer tier.
That score comes from 5 science badges — Galaxy, Outside our galaxy entirely, Has a proper name, Irregular galaxy (no shape at all) and Ghostly low surface brightness — 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.
