HD 219134 f, also known as HR 8832 f, is an exoplanet orbiting around the K-type star HD 219134 in the constellation of Cassiopeia. It is a Super-Earth with a minimum mass of over 7 times that of Earth. Unlike HD 219134 b and HD 219134 c it was not observed by the Spitzer Space Telescope and thus its radius and density are unknown. Only a minimum radius can be given.
