Kepler-14 b
Kepler-14 b is a hot Jupiter orbiting Kepler-14 in the constellation Lyra. It was discovered in 2011 using the transit method.
How Big Is Kepler-14 b?
Kepler-14 b has a radius of 12.73 times that of Earth, or 1.14 times the radius of Jupiter. Its mass is 2,670 times that of Earth, giving it a density of 7.10 g/cm³ — comparable to rocky planets like Earth (5.51 g/cm³).
Is Kepler-14 b in the Habitable Zone?
The position of Kepler-14 b relative to the habitable zone of Kepler-14 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-14: 1.814–4.217 AU (conservative: 2.297–3.998 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-14 b — one full orbit around Kepler-14 — lasts 6.79 Earth days, shorter than Mercury's 88-day year. Its orbit is nearly circular (eccentricity 0.035).
How Was Kepler-14 b Discovered?
Kepler-14 b was discovered in 2011 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.
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-14 b scores 0.07, ranking #4,918 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-14 b
Is Kepler-14 b habitable?
Kepler-14 b is not known to orbit within the habitable zone of Kepler-14, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How big is Kepler-14 b compared to Earth?
Kepler-14 b has 12.73 times the radius of Earth and about 2,670 times its mass.
How long is a year on Kepler-14 b?
One orbit around Kepler-14 takes 6.8 Earth days — short enough that 54 of its years would fit into one Earth year.
