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. This star has a magnitude 9.4 optical companion at an angular separation of 106.6 arcseconds.

Site Editor: HD 219134 c, also known as HR 8832 c, is a hot, dense, rocky exoplanet orbiting around the K-type star HR 8832 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. This set of travel posters envision a day when the creativity of scientists and engineers will allow us to do things we can only dream of now. Teile es! HD 219134 is relatively close to our system, with an estimated distance of 21.25 light years. Its discovery was announced in 2015. As of March 2017, the star is known to have at least 5 planets, with two of them (HD 219134 b and c) known to be transiting, rocky super-Earths. We analyze the interiors of HD 219134 b and c, which are among the coolest super-Earths detected thus far. The innermost planet, HD 219134 b, is a rocky super-Earth based on size (1.6 times the size of Earth), and density (6.4 grams per cubic cm). 2.) HD 219134 c, também conhecido como HR 8832 c, é um exoplaneta que está orbitando em torno de HR 8832, uma estrela anã laranja que está localizada a 21 anos-luz de distância a partir da Terra, na constelação de Cassiopeia. We analyze the interiors of HD~219134~b and c, which are among the coolest super Earths detected thus far. Without using spectroscopic measurements, we aim at constraining if the possible atmospheres are hydrogen-rich or hydrogen-poor. En zweet Astronomenteam ëm de Steven S.

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 f, còn được gọi là HR 8832 f, là một ngoại hành tinh quay quanh sao lùn cam HD 219134 (còn gọi là HR 8832) trong chòm sao Tiên Hậu.Nó là một Siêu Trái Đất có khối lượng tối thiểu hơn 7 lần Trái Đất. HD 219134 c is a super Earth exoplanet that orbits a K-type star. Full table display Database search. Its discovery was announced in 2015. 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. It is smaller and less luminous than our Sun, with a spectral class of K3V, which makes it an orange-hued star. HD 219134 c: Back : Fictional info ; Suggested name: Arat Ytoba: Planet type: Hot planet: Orbiting within Ileno's orbit, Arat Ytoba is an inferior planet and never appears to venture far from HD 219134; its maximum angular distance from HD 219134 (elongation) is 60 degrees.
