Sextans Dwarf Spheroidal is a rare galaxy. It sits in the constellation Sex and shines at apparent magnitude 10.4.
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 Dwarf Spheroidal in the constellation Sex. At apparent magnitude 10.4, a small backyard telescope will bring it into view.
Like any astronomical target, Sextans Dwarf Spheroidal 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 Dwarf Spheroidal scores 43 points on Spacedle's rarity scale, which places it in the rare tier. Another 7 points would lift it into a rarer tier.
That score comes from 5 science badges — Galaxy, Has a proper name, Lenticular galaxy (a disc with no arms), Big on the sky 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.
