Trivia
What makes it special
- Next-door neighbour. One of the closest objects of its kind to the Sun.
Could we get there?
- Verdict. A multi-generation starship could one day attempt the crossing.
Getting there
- Aboard Voyager 1. ≈ 74.3 thousand years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 6600 years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 42.3 years in a starship at a tenth of light speed.
- Distance. 4.2 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 2022.
Saying hello
- Say hello. A radio message and its reply would take 8.5 years round-trip.
How we found it
- Named. Notable enough to have earned a proper name, not just a catalogue number.
