Kepler-114 b
Kepler-114 b is a super-Earth orbiting Kepler-114 in the constellation Cygnus. It lies about 847 light-years from Earth and was discovered in 2014 using the transit method.
How Big Is Kepler-114 b?
Kepler-114 b has a radius of 1.26 times that of Earth.
Is Kepler-114 b in the Habitable Zone?
The position of Kepler-114 b 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 b — one full orbit around Kepler-114 — lasts 5.19 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.053 AU — closer to its star than Mercury is to the Sun.
How Was Kepler-114 b Discovered?
Kepler-114 b 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-114 b?
Kepler-114 b 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 b scores 0.31, ranking #1,203 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-114 b
Is Kepler-114 b habitable?
Kepler-114 b 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 b?
Kepler-114 b 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 b compared to Earth?
Kepler-114 b has 1.26 times the radius of Earth.
How long is a year on Kepler-114 b?
One orbit around Kepler-114 takes 5.2 Earth days — short enough that 70 of its years would fit into one Earth year.
