Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 1.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 151.5 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 970 years in a starship at a tenth of light speed.
- Distance. 97 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1929.
Saying hello
- Say hello. A radio message and its reply would take 194 years round-trip.
How we found it
- Named. Notable enough to have earned a proper name, not just a catalogue number.
