Kepler-114 c
Kepler-114 c is a super-Earth orbiting Kepler-114 in the constellation Cygnus. It lies about 847 light-years from Earth and was discovered in 2013 using the transit method.
How Big Is Kepler-114 c?
Kepler-114 c has a radius of 1.60 times that of Earth. Its mass is 2.8 times that of Earth.
Is Kepler-114 c in the Habitable Zone?
The position of Kepler-114 c relative to the habitable zone of Kepler-114 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on Kepler-114 c — one full orbit around Kepler-114 — lasts 8.04 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-114 c Discovered?
Kepler-114 c was discovered in 2013 using the transit method, with observations from Kepler.
The transit method watches a star for the tiny, regular dip in brightness that occurs when a planet crosses in front of it. The depth and timing of these dips reveal the planet's size and orbital period.
How Far Away Is Kepler-114 c?
Kepler-114 c is 846.5 light-years (259.5 parsecs) from Earth. Light arriving here tonight left the planet around the year 1180. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 14,898,400 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. Kepler-114 c scores 0.30, ranking #1,321 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-114 c
Is Kepler-114 c habitable?
Kepler-114 c is not known to orbit within the habitable zone of Kepler-114, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-114 c?
Kepler-114 c is about 847 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 14,898,400 years to get there.
How big is Kepler-114 c compared to Earth?
Kepler-114 c has 1.60 times the radius of Earth and about 2.8 times its mass.
How long is a year on Kepler-114 c?
One orbit around Kepler-114 takes 8.0 Earth days — short enough that 45 of its years would fit into one Earth year.
