Trivia
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 24.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 2.2 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 14.1 thousand years in a starship at a tenth of light speed.
- Distance. 1406 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 620.
Saying hello
- Say hello. A radio message and its reply would take 2812 years round-trip.
Standing on it
- A year here. A full year lasts just 1.9 Earth days.
By the numbers
- Size. About 2.5× the width of Earth.
- Volume. About 15.3 Earths could fit inside it.
- Mass. About 6.7× the mass of Earth.
- Your weight. You'd weigh about 1.1× your Earth weight standing here.
How we found it
