Trivia

What it actually is

  • Spectral class. Its spectrum reads B0Ib — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.
  • 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 6.8 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Sagittarius.
  • 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 6848 is a rare star

That score comes from 5 science badges — Star, Toward the galactic centre, On the zodiac, Hot blue B-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.
