Kepler-113 c
Kepler-113 c is a super-Earth orbiting Kepler-113 in the constellation Cygnus. It lies about 856 light-years from Earth and was discovered in 2014 using the transit method.
How Big Is Kepler-113 c?
Kepler-113 c has a radius of 2.18 times that of Earth. Its mass is 8.7 times that of Earth.
Is Kepler-113 c in the Habitable Zone?
The position of Kepler-113 c relative to the habitable zone of Kepler-113 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-113: 0.366–0.895 AU (conservative: 0.463–0.848 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-113 c — one full orbit around Kepler-113 — lasts 8.93 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-113 c Discovered?
Kepler-113 c was discovered in 2014 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-113 c?
Kepler-113 c is 855.7 light-years (262.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1171. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 15,060,320 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-113 c scores 0.28, ranking #2,415 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-113 c
Is Kepler-113 c habitable?
Kepler-113 c is not known to orbit within the habitable zone of Kepler-113, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-113 c?
Kepler-113 c is about 856 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 15,060,320 years to get there.
How big is Kepler-113 c compared to Earth?
Kepler-113 c has 2.18 times the radius of Earth and about 8.7 times its mass.
How long is a year on Kepler-113 c?
One orbit around Kepler-113 takes 8.9 Earth days — short enough that 41 of its years would fit into one Earth year.
