Using both the radial velocity and transit method, both its mass and radius have been well determined, allowing for accurate modelling of the planet's composition. The Spitzer Space Telescope detected a transit of the innermost of these planets, HD 219134 b, whose mass and radius (4.5 M ⊕ and 1.6 R ⊕ respectively) are consistent with a rocky composition1.

However, the composition of volatile materials on HD 219134 b and c could not be accurately determined, yet it is believed that the former has a very thin gaseous envelope, far thinner than those of Uranus and Neptune.

HD 219134 h, also known as HR 8832 h, is an exoplanet orbiting around the K-type star HD 219134 in the constellation of Cassiopeia.It has a mass of 108 Earth Masses, which indicates that the planet is likely a gas giant.Unlike HD 219134 b it has not been observed by the Spitzer telescope and thus its radius and density are unknown. It has a temperature of 4699 K and is about 11.0 billion years old, making it one of the oldest stars. We analyze the interiors of HD 219134 b and c, which are among the coolest super-Earths detected thus far. HD 219134 is a K-dwarf star at a distance of 6.5 parsecs around which several low-mass planets were recently discovered 1,2 . 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. "The HARPS-N Rocky Planet Search, I.

HD 219134 b may not be a catchy name - but our new planetary neighbour deserves just as much attention as Earth's cousin, Kepler-452 b. Using both the radial velocity and transit method, both its mass and radius have been well determined, allowing for accurate modelling of the planet's composition. The exoplanet was initially detected by the instrument H The wind velocity at planet ‘b’ is smaller than that at planet ‘c’, because the stellar wind accelerates with distance and planet ‘b’ orbits at a closer distance to the star. The solid lines in Fig. For HD 219134 b, the predicted atmosphere was calculated to reach a height of about 0.18 R⊕ (~1,150 km), below the predicted height of a primordial hydrogen atmosphere (0.28 R⊕).

Using both the radial velocity and transit method, both its mass and radius have been well determined, allowing for accurate modelling of the planet's composition. The Spitzer Space Telescope detected a transit of the innermost of these planets, HD 219134 b, whose mass and radius (4.5 M ⊕ and 1.6 R ⊕ respectively) are consistent with a rocky composition1.

HD 219134 b has a size of about 1.6 R⊕, and a density of 6.4 g/cm3 and orbits at 21.25 light-years away. The ancients debated the existence of planets beyond our own; now we know of thousands. 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/cm3 and 1.85 times the gravity of Earth.

However, the composition of volatile materials on HD 219134 b and c could not be accurately determined, yet it is believed that the former has a very thin gaseous envelope, far thinner than those of Uranus and Neptune. This would indicate a secondary atmosphere produced by processes like volcanic activity and evaporation of volatile materials.

Science Writer: [3] In 2017, it was found that the planet likely hosts an atmosphere. This is consistent with a rocky, Earth-like composition. 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. The star has a mass of 0.81 M☉ and a radius of 0.778 R☉. In comparison, the Sun is 4.6 billion years old[6] and has a temperature of 5778 K.[7]. [8], Coordinates: 23h 13m 16.98s, +57° 10′ 06.1″. Despite its Earth-like composition, the planet's equilibrium temperature is around 1,015 K (742 Â°C; 1,367 Â°F), far too hot for liquid water or life.

In 2017, it was predicted that HD 219134 b and HD 219134 c likely have atmospheres that are secondary in nature, based on the compositions of the planets and the potential for atmospheric escape. [1. HD 219134 b has a size of about 1.6 R ⊕, and a density of 6.4 g/cm 3 and orbits at 21.25 light-years away.

HD219134b: A transiting rocky planet in … HD 219134 b is a super-Earth, an exoplanet with a radius and mass bigger than Earth, but smaller than that of the ice giants Neptune and Uranus. This is relatively unusual, as most planets of ≥1.6 R⊕ are expected to be rich in volatile materials, such as water and gas. 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.
