Der Abstand zu seinem Zentralstern beträgt etwa 0,014 AE (ca. [1][14] Water planets could result from inward planetary migration and originate as protoplanets that formed from volatile ice-rich material beyond the snow-line but that never attained masses sufficient to accrete large amounts of H/He nebular gas. But the world has prepared a lot of surprises. The planet was discovered in December 2009. the interior is assumed to be composed primarily of a water core surrounded by more water, proportions of the total mass consistent with the mass and radius are about 25% rock and 75% water, covered by a thick envelope of gases such as hydrogen and helium (c. & SEAGER S. ApJ. Its equilibrium temperature is believed to be in the range of 393–555 K (120–282 °C; 248–539 °F), depending on how much of the star's radiation is reflected into space. The discovery of a menagerie of exoplanets sized greater than Earth and smaller than Neptune has changed thinking about planets and solar systems. Detailed information on planet GJ 1214 b orbiting around star GJ 1214. Through a comparison with theoretical models, the density in turn provides limited but highly useful information about the composition and structure of the planet.[1]. Gliese 1214 b (thường được rút ngắn thành GJ 1214 b aka Ocean Planet) là một ngoại hành tinh quay quanh ngôi sao Gliese 1214, và được phát hiện vào tháng 12 năm 2009. Gliese 1214 b's national animal is the cobra, which frolics freely in the nation's many lush forests. On the weight of Gliese, 1214 b is 6.55 times the Earth's, and 2.5 times more in diameter. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. C'est la troisième exoplanète découverte dont la taille est inférieure à celle d'une géante gazeuse et la première sur laquelle l'eau pourrait être présent… Top 10%. As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet. [8][9][10][11], GJ 1214 b was first detected by the MEarth Project, which searches for the small drops in brightness that can occur when an orbiting planet briefly passes in front of its parent star. In December 2010, a study was published showing the spectrum to be largely featureless over the wavelength range of 750–1000 nm. As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet. Astronomy Science ~ GJ 1214 b is a Super-Earth planet orbiting GJ 1214. It is a real life planet that has its own wikipedia page here. [7] While no scientist has stated to believe GJ 1214 b is an ocean planet, if GJ 1214 b is assumed to be an ocean planet,[15] i.e. This planet is a super-Earth with a radius of 2.7 Earth radii and 6.5 Earth masses. A search for additional planets using transit timing variations was negative. Another possibility is that there may be a thick layer of high clouds, which absorbs the starlight. Comparative dimensions of Gliese 1214 b. planet koji se sastoji od jezgre i masivnog ocenana, uz planet Kepler-22b. This list shows all planetary and stellar components in the system. Gliese 1214 b[3] (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. The parent star is 42 light-years from the Sun, in the constellation Ophiuchus where its sector name comes from. On the basis of planetary models[15] it has been suggested that GJ 1214 b has a relatively thick gaseous envelope. Seine Masse entspricht knapp 7 Erdmassen, sein Radius wir… Like other ocean planets, it has a surface that is extremely sensitive to the touch of anything, especially asteroids, which means it hates them. Gliese 1214 b is an exoplanet that orbits the star Gliese 1214. Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus. Gliese 1214 (GJ 1214) on 40 valovuoden päässä sijaitseva punainen kääpiötähti, jolla on eksoplaneetta GJ 1214 b.Planeetta kuuluu massaltaan supermaiden … Gliese 1214 b is a planet 48 light-years away from Earth.

On the weight of Gliese, 1214 b is 6.55 times the Earth's, and 2.5 times more in diameter. Like other ocean planets, it has a surface that is extremely sensitive to the touch of anything, especially asteroids, which means it hates them. Elle est située à environ 40 années-lumière du Soleil. [12] Its luminosity is only 0.33% that of the Sun. Astronomers using the Hubble Space Telescope have discovered a new class of alien planets, so-called steamy waterworlds. The star is about one-fifth the radius of the Sun with a surface temperature estimated to be 3 000 K (2 730 °C; 4 940 °F). Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. 2.
