Trivia
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 17.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.6 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 10.2 thousand years in a starship at a tenth of light speed.
- Distance. 1019 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1007.
Saying hello
- Say hello. A radio message and its reply would take 2038 years round-trip.
