Trivia

What makes it special

  • Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 10.5 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 930.5 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 5959 years in a starship at a tenth of light speed.
  • Distance. 596 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1430.

Saying hello

  • Say hello. A radio message and its reply would take 1192 years round-trip.

Standing on it

  • A year here. A full year lasts just 2.1 Earth days.

By the numbers

  • Size. About 13.4× the width of Earth.
  • Volume. About 2406 Earths could fit inside it.
  • Mass. Roughly 598× Earth's mass — about 1.9 Jupiters.
  • Your weight. You'd weigh about 3.3× your Earth weight standing here.
  • Temperature. Around 1031°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by Fred Lawrence Whipple Observatory using the radial velocity method.

Cosmic context

  • Crowded system. One of at least 2 planets orbiting its star.
