Trivia
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 21.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.9 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 12.4 thousand years in a starship at a tenth of light speed.
- Distance. 1238 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 788.
Saying hello
- Say hello. A radio message and its reply would take 2475 years round-trip.
Standing on it
- A year here. A full year lasts just 6.7 Earth days.
By the numbers
- Size. About 1.2× the width of Earth.
- Mass. About 2× the mass of Earth.
- Your weight. You'd weigh about 1.3× your Earth weight standing here.
- Temperature. A scorching 314°C on average.
How we found it
