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. ≈ 3.6 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 318.5 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 2040 years in a starship at a tenth of light speed.
- Distance. 204 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1822.
Saying hello
- Say hello. A radio message and its reply would take 408 years round-trip.
Standing on it
- A year here. A full year lasts just 5.5 Earth days.
By the numbers
- Size. About 1.9× the width of Earth.
- Volume. About 6.4 Earths could fit inside it.
- Mass. About 4.1× the mass of Earth.
- Your weight. You'd weigh about 1.2× your Earth weight standing here.
- Temperature. Around 1041°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by La Silla Observatory using the radial velocity method.
Cosmic context
- Crowded system. One of at least 4 planets orbiting its star.
