The heavy element abundance of 14 Herculis is greater than that of the Sun and the discovery that it has a massive planet lends support to the idea that such large worlds tend to form in heavy element enriched environments. The planetary companion of 14 Herculis has a mass almost five times that of Jupiter and moves in an eccentric orbit about its host star with a period of 4.9 years. This puts it in the category of classical jovians along with the companion of 47 Ursae Majoris, which it most closely resembles. The discovery of second possible planet around 14 Herculis was announced in 2005.
