Trivia

What it actually is

  • Spectral class. Its spectrum reads WNs... — a Wolf-Rayet star: a stellar monster shedding its own outer layers in a ferocious wind, on its way to a supernova.

Sense of scale

  • In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.

Find it in the sky

  • How to spot it. At magnitude 8 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Cygnus.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around July — that's when to go looking.

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 9.9 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 876.5 thousand years even at the Parker Solar Probe's 192 km/s.

Why HD 193077 is a rare star

HD 193077 scores 37 points on Spacedle's rarity scale, which places it in the rare tier. Another 13 points would lift it into a rarer tier.

That score comes from 2 science badges — Star and Wolf-Rayet star (shedding itself) — 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.
