Trivia
What makes it special
- Packed system. Crammed into a system of five or more planets.
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 16.2 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.4 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 9216 years in a starship at a tenth of light speed.
- Distance. 922 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1104.
Saying hello
- Say hello. A radio message and its reply would take 1843 years round-trip.
Standing on it
- A year here. A full year lasts just 6.1 Earth days.
By the numbers
- Size. Around 82% of Earth's width.
- Mass. About 0.8× the mass of Earth.
- Your weight. You'd weigh about 1.1× your Earth weight standing here.
- Temperature. Around 731°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by Kepler using the transit method.
Cosmic context
- Crowded system. One of at least 6 planets orbiting its star.
