Kepler-416 b
Kepler-416 b is a super-Earth orbiting Kepler-416 in the constellation Lyra. It lies about 2,253 light-years from Earth and was discovered in 2014 using the transit timing variations method.
How Big Is Kepler-416 b?
Kepler-416 b has a radius of 2.48 times that of Earth. Its mass is 58.2 times that of Earth.
Is Kepler-416 b in the Habitable Zone?
The position of Kepler-416 b relative to the habitable zone of Kepler-416 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on Kepler-416 b — one full orbit around Kepler-416 — lasts 6.32 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-416 b Discovered?
Kepler-416 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-416 b?
Kepler-416 b is 2,253.1 light-years (690.8 parsecs) from Earth. Light arriving here tonight left the planet about 2,253 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 39,654,560 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-416 b scores 0.24, ranking #3,385 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-416 b
Is Kepler-416 b habitable?
Kepler-416 b is not known to orbit within the habitable zone of Kepler-416, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-416 b?
Kepler-416 b is about 2,253 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 39,654,560 years to get there.
How big is Kepler-416 b compared to Earth?
Kepler-416 b has 2.48 times the radius of Earth and about 58.2 times its mass.
How long is a year on Kepler-416 b?
One orbit around Kepler-416 takes 6.3 Earth days — short enough that 58 of its years would fit into one Earth year.
