Kepler-14 b
Kepler-14 b is a hot Jupiter orbiting Kepler-14 in the constellation Lyra. It lies about 2,603 light-years from Earth and 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.
How Far Away Is Kepler-14 b?
Kepler-14 b is 2,602.7 light-years (798.0 parsecs) from Earth. Light arriving here tonight left the planet about 2,603 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 45,807,520 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-14 b scores 0.07, ranking #4,915 of 5,565 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 far away is Kepler-14 b?
Kepler-14 b is about 2,603 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 45,807,520 years to get there.
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.
