Trivia
What makes it special
- Heavyweight. Packed denser than solid iron.
- Packed system. Crammed into a system of five or more planets.
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 58.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 5.2 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 33.5 thousand years in a starship at a tenth of light speed.
- Distance. 3351 light-years from Earth.
Look-back time
- Look-back time. Its light left before the last ice age ended.
Saying hello
- Say hello. A radio message and its reply would take 6702 years round-trip.
Standing on it
- A year here. A full year lasts just 38 Earth days.
By the numbers
- Size. About 2.6× the width of Earth.
- Volume. About 17.6 Earths could fit inside it.
- Mass. About 27.7× the mass of Earth.
- Your weight. You'd weigh about 4.1× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. A scorching 345°C on average.
How we found it
- Discovery. Found by Kepler using the transit method.
Cosmic context
- Crowded system. One of at least 5 planets orbiting its star.
