Trivia
What makes it special
- Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 19.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.8 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 11.2 thousand years in a starship at a tenth of light speed.
- Distance. 1122 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 904.
Saying hello
- Say hello. A radio message and its reply would take 2243 years round-trip.
Standing on it
- A year here. A full year lasts just 283 Earth days.
By the numbers
- Size. About 9.3× the width of Earth.
- Volume. About 814 Earths could fit inside it.
- Mass. Roughly 87.1× Earth's mass — about 0.3 Jupiters.
- Your weight. You'd weigh about 1.0× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. A surprisingly temperate 22°C average.
How we found it
- Discovery. Found by Kepler using the transit method.
