14 Herculis b or 14 Her b is an exoplanet approximately 58.4 light-years away in the constellation of Hercules. The planet was found orbiting the star 14 Herculis, with a mass that would make the planet a Jovian planet roughly the same size as Jupiter but much more massive. It was discovered in July 1998 by the Geneva Extrasolar Planet Search team.[5][6] The discovery was formally published in 2003.[2] At the time of discovery it was the extrasolar planet with the longest orbital period, though longer-period planets have subsequently been discovered.
