IC 289 is an epic nebula. It lies about 5,193.6 light-years from Earth, sits in the constellation Cas and shines at apparent magnitude 13.2.
A planetary nebula: the shed outer atmosphere of a dying Sun-like star, lit from within by the naked stellar core left behind.
Look for IC 289 in the constellation Cas. At apparent magnitude 13.2, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, IC 289 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 289 scores 55 points on Spacedle's rarity scale, which places it in the epic tier. Another 23 points would lift it into a rarer tier.
That score comes from 7 science badges — Nebula, Distant (over 1,000 light-years), Planetary nebula (a dying star's shell), Never sets (northern circumpolar), Coming towards us, Its dying star is still visible 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.
