Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 181.8 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1164 years in a starship at a tenth of light speed.
  • Distance. 116 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1910.

Saying hello

  • Say hello. A radio message and its reply would take 233 years round-trip.

Standing on it

  • A year here. A full year lasts just 29.3 Earth days.

By the numbers

  • Size. About 1.7× the width of Earth.
  • Volume. About 5.2 Earths could fit inside it.
  • Mass. About 5.8× the mass of Earth.
  • Your weight. You'd weigh about 1.9× your Earth weight standing here.
  • Temperature. A scorching 60°C on average.

How we found it

  • Discovery. Found by CHaracterising ExOPlanets Satellite (CHEOPS) using the transit method.

Cosmic context

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