Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 10.7 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 946.6 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 6062 years in a starship at a tenth of light speed.
  • Distance. 606 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1420.

Saying hello

  • Say hello. A radio message and its reply would take 1212 years round-trip.

Standing on it

  • A year here. A full year lasts just 31.6 Earth days.

By the numbers

  • Size. About 4.6× the width of Earth.
  • Volume. About 95.7 Earths could fit inside it.
  • Mass. About 47.8× the mass of Earth.
  • Your weight. You'd weigh about 2.3× your Earth weight standing here.
  • Temperature. A scorching 378°C on average.

How we found it

  • Discovery. Found by Kepler using the transit method.

Cosmic context

  • Crowded system. One of at least 2 planets orbiting its star.
  • Wild orbit. Its highly elliptical path swings between scorching and frozen each lap.

About Kepler-1656 b

Kepler-1656 b is an uncommon exoplanet. It lies about 606.2 light-years from Earth, has an equilibrium temperature near 651 K, spans roughly 4.57 Earth radii and weighs about 47.8 Earth masses.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, Kepler-1656 b is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why Kepler-1656 b is an uncommon exoplanet

Kepler-1656 b scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Neptune-like, Eccentric orbit, Multi-planet system and Found by Kepler — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
