Trivia

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 47.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 4.2 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 27 thousand years in a starship at a tenth of light speed.
  • Distance. 2696 light-years from Earth.

Look-back time

  • Look-back time. Its light left before the last ice age ended.

Saying hello

  • Say hello. A radio message and its reply would take 5391 years round-trip.

That score comes from 2 science badges — Star and Distant (>1000 ly) — 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.
