Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 4.9 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 434.9 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 2785 years in a starship at a tenth of light speed.
Distance. 279 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1747.

Saying hello

Say hello. A radio message and its reply would take 557 years round-trip.
