IC 4673 is an epic nebula. It lies about 3,875.9 light-years from Earth, sits in the constellation Sgr and shines at apparent magnitude 13.
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 4673 in the constellation Sgr. At apparent magnitude 13, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, IC 4673 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 4673 scores 59 points on Spacedle's rarity scale, which places it in the epic tier. Another 19 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), Toward the galactic centre, On the zodiac, Coming towards us and Its dying star is still visible — 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.
