Trivia

What makes it special

  • Packed system. Crammed into a system of five or more planets.

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 10.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 904.4 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 5792 years in a starship at a tenth of light speed.
  • Distance. 579 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1447.

Saying hello

  • Say hello. A radio message and its reply would take 1158 years round-trip.

Standing on it

  • A year here. A full year lasts just 22.4 Earth days.

By the numbers

  • Size. About 1.3× the width of Earth.
  • Mass. About 2.1× the mass of Earth.
  • Your weight. You'd weigh about 1.3× your Earth weight standing here.
  • Temperature. A surprisingly temperate 46°C average.

How we found it

  • Discovery. Found by Kepler using the transit method.

Cosmic context

  • Crowded system. One of at least 5 planets orbiting its star.
