Kepler-92 b
Kepler-92 b is a super-Earth orbiting Kepler-92 in the constellation Lyra. It lies about 1,559 light-years from Earth and was discovered in 2013 using the transit method.
How Big Is Kepler-92 b?
Kepler-92 b has a radius of 3.51 times that of Earth. Its mass is 64.3 times that of Earth.
Is Kepler-92 b in the Habitable Zone?
The position of Kepler-92 b relative to the habitable zone of Kepler-92 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on Kepler-92 b — one full orbit around Kepler-92 — lasts 13.7 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-92 b Discovered?
Kepler-92 b 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-92 b?
Kepler-92 b is 1,559.0 light-years (478.0 parsecs) from Earth. Light arriving here tonight left the planet about 1,559 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 27,438,400 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-92 b scores 0.20, ranking #3,919 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-92 b
Is Kepler-92 b habitable?
Kepler-92 b is not known to orbit within the habitable zone of Kepler-92, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-92 b?
Kepler-92 b is about 1,559 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 27,438,400 years to get there.
How big is Kepler-92 b compared to Earth?
Kepler-92 b has 3.51 times the radius of Earth and about 64.3 times its mass.
How long is a year on Kepler-92 b?
One orbit around Kepler-92 takes 13.7 Earth days — short enough that 27 of its years would fit into one Earth year.
