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. Spitzer observations allowed the discoverers to detect the transit of the innermost planet in front of the star making HD 219134 b the nearest known transiting planet to date. 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. Kepler-69c troddes också vara beboelig, fast senare visades det att den kan vara som Venus, en varm, obeboelig planet. The star is … This table lists all planets in the system HD 219134. The host star is a metal-rich K3 dwarf located only 6.55 parsecs away (21 light years) in the direction of Cassiopeia. [13][14] Two months later, Vogt et al. You can also view all commits contributing to this file on github. The planetary system HD 219134 hosts at least 7 planets. Full table display Database search. In the HARPS-N solution, this planet was designated HD 219134 e and was assigned a shorter-period, more eccentric orbit. HD 219134 hosts several planets, with seven candidates reported, and the two shortest period planets are rocky (4-5 M ⊕ ) and transit the star. This list shows all planetary and stellar components in the system. You can also download the entire catalogue over at github. This is only an estimate, using the star's spectral type and mass. If you prefer to download the dataset as an ASCII tables, you might find the oec_tables repository useful. This is relatively unusual, as most planets of ≥1.6 R⊕ are expected to be rich in … Please include the reference to the relevant scientific paper in your commit message.

ApJ, accepted arxiv Bayesian analysis of interiors of HD 219134b, Kepler-10b, Kepler-93b, CoRoT-7b, 55 Cnc e, and HD 97658b using stellar abundance proxies The planetary system HD 219134 hosts at least 7 planets. It is in a 2:1 resonance with the warm N-class planet Esker (HD 219134 g), making a full revolution in around 188 days, and was discovered in 2039 CE via the radial velocity method.
