HD 180275 is an epic variable star. It lies about 1,136.4 light-years from Earth, sits in the constellation Sgr, shines at apparent magnitude 7.91 and has spectral type M2e.
Its spectrum reads M2e — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.
Look for HD 180275 in the constellation Sgr. At apparent magnitude 7.91, it is an easy target for binoculars.
Like any astronomical target, HD 180275 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.
HD 180275 scores 72 points on Spacedle's rarity scale, which places it in the epic tier. Another 6 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Distant (over 1,000 light-years), Toward the galactic centre, On the zodiac, Cool red M-type star, Red dwarf, Dramatic variable (over 2 magnitudes) and Fades out of naked-eye view — 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.
