Trivia

What it actually is

  • Spectral class. Its spectrum reads O9Ib — 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.
  • Where it is in life. It is a supergiant, hundreds of times wider than the Sun.

Find it in the sky

  • How to spot it. At magnitude 6.5 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Scorpius.
  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • Best time of year. It stands highest in the middle of the night around June — that's when to go looking.

What's in a name

  • Its catalogue. The HR number is from the Bright Star Catalogue — roughly 9,100 stars, essentially everything the unaided eye can see.

Why HR 6263 is an epic star

That score comes from 4 science badges — Star, On the zodiac, Blazing O-type star and Supergiant — 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.
