Trivia

What makes it special

  • Frozen world. A deep-frozen world far from its star's warmth.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 1.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 107.9 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 691 years in a starship at a tenth of light speed.
  • Distance. 69.1 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1957.

Saying hello

  • Say hello. A radio message and its reply would take 138 years round-trip.

Standing on it

  • A year here. A full year lasts about 11.9 Earth years.

By the numbers

  • Size. About 13× the width of Earth.
  • Volume. About 2197 Earths could fit inside it.
  • Mass. Roughly 1335× Earth's mass — about 4.2 Jupiters.
  • Your weight. You'd weigh about 7.9× your Earth weight standing here.
  • Temperature. A frigid -237°C — colder than dry ice.

How we found it

  • Discovery. Found by Leoncito Astronomical Complex using the eclipse timing variations method.
