Trivia
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 91.4 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 8.1 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 52 thousand years in a starship at a tenth of light speed.
- Distance. 5201 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 10.4 thousand years round-trip.
Standing on it
- A year here. A full year lasts just 20.7 Earth days.
By the numbers
- Size. About 4.2× the width of Earth.
- Volume. About 74.1 Earths could fit inside it.
- Mass. About 16.4× the mass of Earth.
- Your weight. You'd weigh about 0.9× your Earth weight standing here.
- Temperature. Around 525°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 2 planets orbiting its star.
