NGC 4589 is an uncommon galaxy. It lies about 90,948,539.8 light-years from Earth, sits in the constellation Dra and shines at apparent magnitude 10.74.
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 4589 in the constellation Dra. At apparent magnitude 10.74, a small backyard telescope will bring it into view.
Like any astronomical target, NGC 4589 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 4589 scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.
That score comes from 4 science badges — Galaxy, Outside our galaxy entirely, Elliptical galaxy and Never sets (northern circumpolar) — 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.
