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 (also known as Gliese 892 or HR 8832) is a main-sequence star in the constellation of Cassiopeia. It gives a quick overview of the hierarchical architecture. [10] 슈퍼지구의 일종으로 지구지름의 약 1.6배이며, 질량은 약 4배 수준이다. It is smaller and less luminous than our Sun, with a spectral class of K3V, which makes it an orange-hued star. 2014). 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. Transits of the second planet were detected in 2017. The following plot shows the approximate sizes of the planets in this system 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. The inner planet orbits the star in 3.0935 ± 0.0003 days, on a quasi-circular orbit with a semi-major axis of 0.0382 ± 0.0003 AU. Within the commit message, you will find a link to the scientific publication where the data is taken from. This table lists all links which are relevant to this particular system. The two components are designated Eta Cassiopeiae A and B. [13][14] Two months later, Vogt et al. 2012). This table lists all planets in the system HD 219134. Its key measurements have been pinned down very precisely, which thus allows a more precise determination of the properties of its accompanying planets. A. Johnson,2 C.T.

It was subsequently shown to be the same candidate as HD 219134 h from Vogt et al. HD 219134 is currently the 99th nearest known stellar system, 7 and as a consequence, any planetary system that it harbors would rank among the 10 closest known systems (a plurality of which orbit much dimmer M-dwarf primaries). HD 219134 is relatively close to our system, with an estimated distance of 21.25 light years. 2017) and represent together the coolest super-Earth pair yet detected in a star system (Figure 1). 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.

The star is … HD 219134 is relatively close to our system, with an estimated distance of 21.25 light years. Two of which fall in the super-Earth regime. This star has a magnitude 9.4 optical companion at an angular separation of 106.6 arcseconds. [18][verification needed], Coordinates: 23h 13m 16.98s, +57° 10′ 06.1″, "Chromospheric activity and rotation of FGK stars in the solar vicinity. The Solar System planets are shown as a comparison. Schulze,1 Ji Wang (‰ ),2 J. Spitzer observations allowed us to detect the transit of the planet in front of the star making HD 219134 b the nearest known transiting planet to date. ("This sky map shows the location of the star HD 219134 (circle), host to the nearest confirmed rocky planet found to date outside of our solar system.The star lies just off the 'W' shape of the constellation Cassiopeia and can be seen with the naked eye in dark skies. This planet was designated HD 219134 d in the HARPS-N announcement. For HD 219134, a period of about 20 days would imply an age of about 1.3 billion years. HD 219134b: Close, Hot, and 'Worth its Weight in Gold' (From NASA/JPL-Caltech/DSS, used w/o permission.) The limit is considered to be magnitude 6 for most observers.
