HD 219134 b (or HR 8832 b) is one of at least five exoplanets orbiting HD 219134, a main-sequence star in the constellation of Cassiopeia. HD 219134 b ist ein Exoplanet, der den rund 21 Lichtjahre von der Sonne entfernten Hauptreihenstern HR 8832 (auch HD 219134) im Sternbild Kassiopeia umkreist. Ele tem uma baixa massa de 2,67 massas terrestres que indica que o exoplaneta é provavelmente um planeta rochoso. HD 219134 c, also known as HR 8832 c, is a hot, dense, rocky exoplanet orbiting around the K-type star HD 219134 in the constellation of Cassiopeia.Originally thought to be a little less than three times the mass of Earth, it is now known to be over 4 times the mass and 51% larger in radius, suggesting a rocky composition with a higher quantity of iron than Earth.
