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. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 3.8 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 338.3 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 2167 years in a starship at a tenth of light speed.
- Distance. 217 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1809.
Saying hello
- Say hello. A radio message and its reply would take 433 years round-trip.
Standing on it
- A year here. A full year lasts just 24.2 Earth days.
By the numbers
- Size. About 1.3× the width of Earth.
- Mass. About 2.2× the mass of Earth.
- Your weight. You'd weigh about 1.3× your Earth weight standing here.
- Temperature. A surprisingly temperate 13°C average.
How we found it
- Discovery. Found by K2 using the transit method.
Cosmic context
- Crowded system. One of at least 4 planets orbiting its star.
