Trivia
What makes it special
- Cotton-candy planet. So low-density it would float on water.
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 17.8 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.6 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 10.2 thousand years in a starship at a tenth of light speed.
- Distance. 1015 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1011.
Saying hello
- Say hello. A radio message and its reply would take 2030 years round-trip.
Standing on it
- A year here. A full year lasts just 18.6 Earth days.
By the numbers
- Size. About 1.6× the width of Earth.
- Mass. About 1× the mass of Earth.
- Your weight. You'd weigh about 0.4× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. A scorching 98°C on average.
How we found it
- Discovery. Found by Kepler using the transit method.
Cosmic context
- Crowded system. One of at least 4 planets orbiting its star.
