1.) Science Writer: Query : HD 219134 : C.D.S. HD 219134 c is a super Earth exoplanet that orbits a K-type star. It has a minimum mass of 11 Earth Masses, suggesting that it could be a high-mass ocean planet or a Neptune-like ice giant. We analyze the interiors of HD~219134~b and c, which are among the coolest super Earths detected thus far. We analyze the interiors of HD 219134 b and c, which are among the coolest super-Earths detected thus far. It is smaller and less luminous than our Sun, with a spectral class of K3V, which makes it an orange-hued star.
