Kepler-414 b
Kepler-414 b is a super-Earth orbiting Kepler-414 in the constellation Cygnus. It lies about 1,349 light-years from Earth and was discovered in 2014 using the transit timing variations method.
How Big Is Kepler-414 b?
Kepler-414 b has a radius of 1.71 times that of Earth. Its mass is 3.5 times that of Earth.
Is Kepler-414 b in the Habitable Zone?
The position of Kepler-414 b relative to the habitable zone of Kepler-414 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on Kepler-414 b — one full orbit around Kepler-414 — lasts 4.70 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-414 b Discovered?
Kepler-414 b was discovered in 2014 using the transit timing variations method, with observations from Kepler.
Transit timing variations reveal a planet through its gravitational tug on a sibling planet, which makes that sibling's transits arrive slightly early or late. The pattern of these deviations betrays the hidden planet's mass and orbit.
How Far Away Is Kepler-414 b?
Kepler-414 b is 1,348.5 light-years (413.5 parsecs) from Earth. Light arriving here tonight left the planet about 1,349 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 23,733,600 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-414 b scores 0.27, ranking #2,440 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-414 b
Is Kepler-414 b habitable?
Kepler-414 b is not known to orbit within the habitable zone of Kepler-414, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-414 b?
Kepler-414 b is about 1,349 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 23,733,600 years to get there.
How big is Kepler-414 b compared to Earth?
Kepler-414 b has 1.71 times the radius of Earth and about 3.5 times its mass.
How long is a year on Kepler-414 b?
One orbit around Kepler-414 takes 4.7 Earth days — short enough that 78 of its years would fit into one Earth year.
