HD 219134 h

HD 219134 h, also known as HR 8832 h, is an exoplanet orbiting around the K-type star HD 219134 in the constellation of Cassiopeia. It has a mass of 108 Earth Masses, which indicates that the planet is likely a gas giant. Unlike HD 219134 b it was not observed by the Spitzer telescope and thus its radius and density are unknown. It is in the ammonia habitable zone, so if it has a large moon with an atmosphere, liquid ammonia could flow on the moon's surface.
