Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 20 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.8 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 11.4 thousand years in a starship at a tenth of light speed.
Distance. 1140 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 886.

Saying hello

Say hello. A radio message and its reply would take 2281 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.
