Could we get there?
- Verdict. A multi-generation starship could one day attempt the crossing.
Getting there
- Aboard Voyager 1. ≈ 104.7 thousand years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 9302 years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 59.6 years in a starship at a tenth of light speed.
- Distance. 6 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 2020.
Saying hello
- Say hello. A radio message and its reply would take 11.9 years round-trip.
Standing on it

By the numbers
- Size. Around 64% of Earth's width.
- Mass. About 0.2× the mass of Earth.
- Your weight. You'd weigh about 0.5× your Earth weight standing here.
- Temperature. A scorching 67°C on average.
How we found it
