(2015). Eta Cassiopeiae is a binary star system in the northern circumpolar constellation of Cassiopeia. Here, we present contemporaneous multiwavelength observations of the star HD 219134. HD 219134 b has a radius of 1.602 R⊕ and a mass of 4.74 M⊕, giving it a density of about 6.4 g/cm 3 and 1.85 times the gravity of Earth. [17] A previously reported planet, HD 219134 g, was not found in following HARPS-N analyses in March 2017 by Gillon et al. 2014). All information on this page has been directly generated from this XML file. 2015; Gillon et al. HD 219134 hosts several planets, with seven candidates reported, and the two shortest period planets are rocky (4-5 M ⊕ ) and transit the star. It was subsequently shown to be the same candidate as HD 219134 h from Vogt et al. Tools. HD 219134 (also known as Gliese 892 or HR 8832) is a main-sequence star in the constellation of Cassiopeia. This is relatively unusual, as most planets of ≥1.6 R⊕ are expected to be rich in … 2012). The limit is considered to be magnitude 6 for most observers. This is only an estimate, using the star's spectral type and mass. Note that this is a new feature and not all system parameters might have a reference associated with it yet. If you prefer to download the dataset as an ASCII tables, you might find the oec_tables repository useful. This is consistent with a rocky, Earth-like composition.

If you spot an error or if you can contribute additional data to this entry, please send an e-mail to exoplanet@hanno-rein.de. Note that unless the radius has been determined through a transit observation, this is only an approximation (see Lissauer et al. The planet candidate HD 219134 e was discovered by Motalebi et al. Its key measurements have been pinned down very precisely, which thus allows a more precise determination of the properties of its accompanying planets. 2. Fresh from their discovery of four new Earth-size planets transiting TRAPPIST-1 (a minuscule M dwarf in the Sun’s back yard), Michaël Gillon & colleagues have contributed exciting new data to our developing picture of another nearby exoplanetary system: HD 219134.

HD 219134 b (även HR 8832 b, Gliese 892 b) är en av fyra exoplaneter i omloppsbana runt stjärnan Gliese 892.Den upptäcktes 2015 med hjälp av Spitzerteleskopet, och gör den till den närmaste stenplaneten från Jorden räknat. published a paper on this system which found a 6-planet solution, with planets b & c corresponding to those in Motalebi et al., e & g corresponding to Motalebi's d & e, and d & f being new planets. For HD 219134, a period of about 20 days would imply an age of about 1.3 billion years. HD 219134 is an orange Type K star somewhat cooler, smaller and less massive than our Sun. HD 219134 g, also known as HR 8832 g, is an unconfirmed exoplanet orbiting around the K-type star HR 8832 in the constellation of Cassiopeia.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.Unlike HD 219134 b and HD 219134 c it has not been observed by the Spitzer Space Telescope and thus its radius and density are unknown. If the actual C/O ratio of HD 219134 was outside the range of 0.25–0.75, our calculated disc chemistry could significantly differ. If you are fluent with git and github, you can also create a pull request or open an issue on the Open Exoplanet Catalogue repository. HD 219134 is relatively close to our system, with an estimated distance of 21.25 light years. This is consistent with a rocky, Earth-like composition. HD 219134 is relatively close to our system, with an estimated distance of 21.25 light years. HD 219134 with its four low-mass planets is the first result of the Rocky Planet Search program with HARPS-N on the Telescopio Nazionale Galileo in La Palma.
