Trivia

What makes it special

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

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 17.6 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 thousand years in a starship at a tenth of light speed.
  • Distance. 1000 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1026.

Saying hello

  • Say hello. A radio message and its reply would take 2001 years round-trip.

Standing on it

  • A year here. A full year lasts about 2.7 Earth years.

By the numbers

  • Size. About 13.4× the width of Earth.
  • Volume. About 2406 Earths could fit inside it.
  • Mass. Roughly 657× Earth's mass — about 2.1 Jupiters.
  • Your weight. You'd weigh about 3.7× your Earth weight standing here.
  • Temperature. A frigid -102°C — colder than dry ice.

How we found it

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

Cosmic context

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