HD 219134 c

HD 219134 c, also known as HR 8832 c, is an exoplanet orbiting around the K-type star HR 8832 in the constellation of Cassiopeia. It has a low mass of 2.67 Earth Masses, which indicates that the exoplanet is likely a rocky planet. Due to its short orbital period - just under 7 days - it is too hot to have liquid water on its surface. The exoplanet was initially detected by the instrument HARPS-N of the Italian Telescopio Nazionale Galileo via the radial velocity method.
