HR 6245 is a rare variable star. It sits in the constellation Sco, shines at apparent magnitude 5.23 and has spectral type O9e.
Its spectrum reads O9e — 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 6245 in the constellation Sco. At apparent magnitude 5.23, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 6245 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 6245 scores 47 points on Spacedle's rarity scale, which places it in the rare tier. Another 3 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Naked-eye visible, On the zodiac, Blazing O-type star, Barely variable (under 0.05 mag) and A named variable star — 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.
