Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 2.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 241.4 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 1546 years in a starship at a tenth of light speed.
- Distance. 155 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1871.
Saying hello
- Say hello. A radio message and its reply would take 309 years round-trip.
Standing on it
- A year here. A full year lasts just 415 Earth days.
By the numbers
- Size. About 13.7× the width of Earth.
- Volume. About 2571 Earths could fit inside it.
- Mass. Roughly 358× Earth's mass — about 1.1 Jupiters.
- Your weight. You'd weigh about 1.9× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. Around 448°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by Okayama Astrophysical Observatory using the radial velocity method.
Cosmic context
- Crowded system. One of at least 2 planets orbiting its star.
