Trivia
What makes it special
- Heavyweight. Packed denser than solid iron.
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 31.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 2.8 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 18 thousand years in a starship at a tenth of light speed.
- Distance. 1803 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 223.
Saying hello
- Say hello. A radio message and its reply would take 3606 years round-trip.
Standing on it
- A year here. A full year lasts just 9.3 Earth days.
By the numbers
- Size. About 1.6× the width of Earth.
- Mass. About 8.5× the mass of Earth.
- Your weight. You'd weigh about 3.5× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. Around 870°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by Kepler using the transit timing variations method.
Cosmic context
- Crowded system. One of at least 4 planets orbiting its star.
