CoRoT-14 b
CoRoT-14 b is a hot Jupiter orbiting the F9 V star CoRoT-14 in the constellation Monoceros. It lies about 5,690 light-years from Earth and was discovered in 2010 using the transit method.
How Big Is CoRoT-14 b?
CoRoT-14 b has a radius of 12.22 times that of Earth, or 1.09 times the radius of Jupiter. Its mass is 2,415 times that of Earth, giving it a density of 7.30 g/cm³ — comparable to rocky planets like Earth (5.51 g/cm³).
Is CoRoT-14 b in the Habitable Zone?
CoRoT-14 b orbits inside the inner edge of the habitable zone of CoRoT-14. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of CoRoT-14: 0.975–2.283 AU (conservative: 1.235–2.165 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on CoRoT-14 b
The equilibrium temperature of CoRoT-14 b is about 1,952 K (1,679 °C) — hot enough to melt many metals. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
A year on CoRoT-14 b — one full orbit around CoRoT-14 — lasts just 36.3 hours, shorter than Mercury's 88-day year. It orbits at an average distance of 0.027 AU — closer to its star than Mercury is to the Sun.
How Was CoRoT-14 b Discovered?
CoRoT-14 b was discovered in 2010 using the transit method, with observations from CoRoT.
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 CoRoT-14 b?
CoRoT-14 b is 5,690.1 light-years (1,744.6 parsecs) from Earth. Light arriving here tonight left the planet about 5,690 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 100,145,760 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. CoRoT-14 b scores 0.07, ranking #4,853 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About CoRoT-14 b
Is CoRoT-14 b habitable?
No — CoRoT-14 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is CoRoT-14 b?
CoRoT-14 b is about 5,690 light-years from Earth in the constellation Monoceros. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 100,145,760 years to get there.
How big is CoRoT-14 b compared to Earth?
CoRoT-14 b has 12.22 times the radius of Earth and about 2,415 times its mass.
How long is a year on CoRoT-14 b?
One orbit around CoRoT-14 takes 1.5 Earth days — short enough that 242 of its years would fit into one Earth year.
