Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 15.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.4 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 8768 years in a starship at a tenth of light speed.
  • Distance. 877 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1149.

Saying hello

  • Say hello. A radio message and its reply would take 1754 years round-trip.
