Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 17.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.5 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 9906 years in a starship at a tenth of light speed.
  • Distance. 991 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1035.

Saying hello

  • Say hello. A radio message and its reply would take 1981 years round-trip.

Standing on it

  • A year here. A full year lasts just 259 Earth days.

By the numbers

  • Size. About 13.9× the width of Earth.
  • Volume. About 2686 Earths could fit inside it.
  • Mass. Roughly 260× Earth's mass — about 0.8 Jupiters.
  • Your weight. You'd weigh about 1.3× your Earth weight standing here.
  • Density. Less dense than water — drop it in a big enough ocean and it would float.
  • Temperature. A scorching 116°C on average.

How we found it

  • Discovery. Found by W. M. Keck Observatory using the radial velocity method.

Cosmic context

  • Crowded system. One of at least 4 planets orbiting its star.
