Trivia
What makes it special
- Lava world. Its surface is likely an ocean of molten rock.
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 17 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.5 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 9702 years in a starship at a tenth of light speed.
- Distance. 970 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1056.
Saying hello
- Say hello. A radio message and its reply would take 1940 years round-trip.
Standing on it
- A year here. A full year lasts just 4.5 Earth days.
By the numbers
- Size. About 14.7× the width of Earth.
- Volume. About 3195 Earths could fit inside it.
- Mass. Roughly 186× Earth's mass — about 0.6 Jupiters.
- Your weight. You'd weigh about 0.9× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. Around 1069°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by SuperWASP using the transit method.
