Kepler-107 c
Kepler-107 c is a confirmed rocky exoplanet 1,716 ly from Earth in the constellation Cygnus, discovered in 2014 by Kepler.
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it (what that means).
Its yellow, Sun-like star looks 23.8× wider than ours, bathing the surface in warm white light. It is likely tidally locked, so that sun never moves in the sky: one hemisphere in endless day, the other in permanent night. A year passes in just 4.9 days, and at an estimated 1105°C (2021°F) it is hot enough to melt rock.
Catalog values (NASA Exoplanet Archive): mass 10.00 M⊕, radius 1.60 R⊕. Its catalog mass and radius imply a density of 13.5 g/cm³, denser than compressed iron, so they cannot both be right, and gravityfinder does not use Kepler-107 c in gravity rankings or weight calculations.

Your voice would sound high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 1105°C (2021°F), sound would travel roughly 119% faster than on Earth, so your voice would sound high and thin, almost cartoonish. The real atmosphere is unknown, so this is a best guess.

- !At about 1105°C (2021°F), the daytime side glows: metals run liquid and any atmosphere is being torn away.
- !Its star delivers about 602 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Earth-similarity index 0.15: this world has almost nothing in common with our own.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.

How far is Kepler-107 c from Earth?
Kepler-107 c lies about 1,716 light-years from Earth.
How long would it take to get to Kepler-107 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 2.7 million years.
How hot is Kepler-107 c?
Kepler-107 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 1105°C (2021°F).
How long is a year on Kepler-107 c?
Kepler-107 c completes one orbit of its star in 4.9 days.
