Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 384.7 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 34.2 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 219 years in a starship at a tenth of light speed.
  • Distance. 21.9 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 2004.

Saying hello

  • Say hello. A radio message and its reply would take 43.8 years round-trip.
