14 Herculis c or 14 Her c is an extrasolar planet approximately 59 light-years away in the constellation of Hercules. The planet was found orbiting the star 14 Herculis, with a mass that would likely make the planet a gas giant roughly the same size as Jupiter but much more massive. This planet was discovered on November 17, 2005 and confirmed on November 2, 2006.[2] According to a recent analysis, the existence of a second planet in the 14 Herculis system is "clearly" supported by the evidence, but the planet's parameters are not precisely known. It may be in a 4:1 resonance with the inner planet 14 Herculis b.[1]
