HD 219134 g, also known as HR 8832 g, is an exoplanet orbiting around the K-type star HR 8832 in the constellation of Cassiopeia. It has a mass of 11 Earth Masses. Unlike HD 219134 b it has not been observed by the Spitzer telescope and thus its radius and density are unknown. It may be in the habitable zone. If it has an Earth-like composition, it would have a radius 1.9 times that of Earth.

Star HR 8832 (circled) lies just off the "W" shape of the constellation Cassiopeia.
