Trivia
What makes it special
- 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. ≈ 51.8 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 4.6 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 29.5 thousand years in a starship at a tenth of light speed.
- Distance. 2950 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 5899 years round-trip.
Standing on it
- A year here. A full year lasts just 26.4 Earth days.
By the numbers
- Size. About 4.1× the width of Earth.
- Volume. About 67.4 Earths could fit inside it.
- Mass. About 12.2× the mass of Earth.
- Your weight. You'd weigh about 0.7× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. A scorching 289°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.
