Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 1.8 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 162.3 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1039 years in a starship at a tenth of light speed.
  • Distance. 104 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1922.

Saying hello

  • Say hello. A radio message and its reply would take 208 years round-trip.

How we found it

  • Named. Notable enough to have earned a proper name, not just a catalogue number.
