14 Herculis is an orange K-type main-sequence dwarf star, located 57 light years from Earth in the constellation Hercules. Due to its apparent magnitude, it cannot be seen with the naked eye from Earth. As of 2006, 14 Herculis has two confirmed extrasolar planets.
14 Herculis is an orange dwarf star of the spectral type K0V. It is thought that the star has 90 percent of the mass, 71 percent of the radius, and only 36 percent of the luminosity of the Sun. The star appears to be 2.7 times as enriched with elements heavier than hydrogen (based on its abundance of iron), in comparison to the Sun.
In 1998, a planet was discovered around 14 Herculis. The planet's eccentric orbital period is 4.8 years. In 2005, a possible second planet was proposed, named 14 Herculis c. The parameters of this planet are not certain but a recent analysis suggests it might lie in the 4:1 resonance with the inner planet, with an orbital period of almost 19 years at an orbital distance of 6.9 AU.
