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. ≈ 13.1 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.2 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 7458 years in a starship at a tenth of light speed.
- Distance. 746 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1280.
Saying hello
- Say hello. A radio message and its reply would take 1492 years round-trip.
Standing on it
- A year here. A full year lasts just 25.5 Earth days.
By the numbers
- Size. Around 84% of Earth's width.
- Mass. About 8.2× the mass of Earth.
- Your weight. You'd weigh about 11.7× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. A scorching 342°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.

How to see it
Like any astronomical target, Kepler-131 c 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-131 c is an epic exoplanet
Kepler-131 c scores 48 points on Spacedle's rarity scale, which places it in the epic tier. Another 20 points would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Earth-sized, Denser than iron, 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.
