Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 6.2 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 547.6 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 3507 years in a starship at a tenth of light speed.
- Distance. 351 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1675.
Saying hello
- Say hello. A radio message and its reply would take 701 years round-trip.
Standing on it

By the numbers
- Size. About 1.7× the width of Earth.
- Volume. About 5.2 Earths could fit inside it.
- Mass. About 6.9× the mass of Earth.
- Your weight. You'd weigh about 2.3× your Earth weight standing here.
- Temperature. Around 640°C — hotter than a self-cleaning oven.
