Trivia

What makes it special

  • Lava world. Its surface is almost certainly an ocean of molten rock, kept liquid by the star it hugs.

Hard to believe

  • Denser than iron. It is packed tighter than solid iron — whatever it is made of, it is not ordinary rock.

What it actually is

  • Hugging its star. It orbits closer to its star than Mercury does to the Sun, completing a lap in less time than Mercury takes.
  • What it is made of. Denser than Earth — a solid world of rock and iron, with no meaningful atmosphere to speak of by mass.
  • Crowded system. One of at least 4 planets orbiting its star.

Sense of scale

  • In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.

Find it in the sky

  • How to spot it. At magnitude 12.5 it is far too faint for the eye: this one belongs to cameras and long exposures.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.

About Kepler-107 c

Kepler-107 c is an anomaly exoplanet. It lies about 1,715.6 light-years from Earth, shines at apparent magnitude 12.54, has an equilibrium temperature near 1,378 K and spans roughly 1.6 Earth radii.

Its surface is almost certainly an ocean of molten rock, kept liquid by the star it hugs.

How to see it

At apparent magnitude 12.54, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, Kepler-107 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-107 c is an anomaly exoplanet

Kepler-107 c scores 78 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 42 points would lift it into a rarer tier.

That score comes from 9 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Super-Earth, Lava world, Tidally locked, 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.
