Kepler-14b es un planeta extrasolar orbitando la estrella binaria Kepler-14 en la constelación de Lyra. Tiene una masa poco mayor que 8 masas jovianas y un radio ligeramente superior al de Júpiter, lo que indica que el planeta posee una considerable densidad respecto a éste.[1]

[en] Kepler-14b

Kepler-14b is an extrasolar planet in orbit around the primary star of the binary Kepler-14 system. It is currently the only planet known to exist in this star system. Kepler-14b is 8.4 times the mass of Jupiter and has a radius 1.14 times that of Jupiter, and it orbits its host star every 6.79 days.[1] It was discovered by NASA-led Kepler mission, which noted the planet as a planetary candidate as early as March 2009, around the same time as the discovery of the first five planets discovered by Kepler (Kepler-4b to Kepler-8b). However, the team was unable to confirm the planet until extensive follow-up observations, as high-resolution imaging resolved the star Kepler-14 as a closely orbiting binary system. The Kepler team would have not noticed that Kepler-14 was a binary star based solely on initial radial velocity measurements (a standard method for confirming a planet's existence), and found that if they had not realized this, their data on Kepler-14b would have been very inaccurate.
