Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 47 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 4.2 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 26.7 thousand years in a starship at a tenth of light speed.
Distance. 2673 light-years from Earth.

Look-back time

Look-back time. Its light left before the last ice age ended.

Saying hello

Say hello. A radio message and its reply would take 5347 years round-trip.
