Trivia

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 24.9 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2.2 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 14.2 thousand years in a starship at a tenth of light speed.
  • Distance. 1418 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 608.

Saying hello

  • Say hello. A radio message and its reply would take 2835 years round-trip.

Standing on it

  • A year here. A full year lasts just 1.5 Earth days.

By the numbers

  • Size. About 1.2× the width of Earth.
  • Mass. About 1.9× the mass of Earth.
  • Your weight. You'd weigh about 1.3× your Earth weight standing here.
  • Temperature. Around 864°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 4 planets orbiting its star.
