Trivia

What makes it special

  • Heavyweight. Packed denser than solid iron.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 3.9 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 347.2 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 2224 years in a starship at a tenth of light speed.
  • Distance. 222 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1804.

Saying hello

  • Say hello. A radio message and its reply would take 445 years round-trip.

Standing on it

  • A year here. A full year lasts just 69 Earth days.

By the numbers

  • Size. About 1.2× the width of Earth.
  • Mass. About 6× the mass of Earth.
  • Your weight. You'd weigh about 4.2× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. A scorching 165°C on average.

How we found it

  • Discovery. Found by Kepler using the transit method.
