HR 6841 is an epic star. It lies about 2,051.3 light-years from Earth, sits in the constellation Sgr, shines at apparent magnitude 6.52 and has spectral type O8/O9.
Its spectrum reads O8/O9 — an O-type star — the hottest, rarest main class there is. Fewer than one star in a million is an O, and none of them lasts long.
Look for HR 6841 in the constellation Sgr. At apparent magnitude 6.52, it is an easy target for binoculars.
Like any astronomical target, HR 6841 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.
HR 6841 scores 56 points on Spacedle's rarity scale, which places it in the epic tier. Another 22 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Distant (over 1,000 light-years), Toward the galactic centre, On the zodiac, Blazing O-type star and Intrinsically luminous (Mv < −2) — 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.
