Like other ocean planets, it has a surface that is extremely sensitive to the touch of anything, especially asteroids, which means it hates them. [7] Some of the solid-phase water could be in the form of ice VII. It is a large-sized (3x larger than earth) water planet that is almost entirely made of boiling ocean water. In December 2010, a study was published showing the spectrum to be largely featureless over the wavelength range of 750–1000 nm. Astronomers using the Hubble Space Telescope have discovered a new class of alien planets, so-called steamy waterworlds. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. Media in category "GJ 1214 b" The following 18 files are in this category, out of 18 total. The inner boundary of Gliese 1214’s habitable zone is 0.05 Au’s from the star and its outer boundary is 0.08 AU’s from the star. The parent star is 42 light-years from the Sun, in the constellation Ophiuchus where its sector name comes from. Based on the spectral type (M4.5) of the star, the star's colour is red . Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus.

[4][5] For that reason, scientists have nicknamed the planet "the waterworld". Gliese 1214 b, também conhecido como GJ 1214 b, é um planeta extrasolar que orbita a estrela Gliese 1214, a uma distância de 13 parsecs ou aproximadamente 40 anos-luz da Terra, na constelação Ophiuchus.Esta superterra tem 6 vezes a massa da Terra e 2,6 vezes o seu raio. The description is based on the spectral class. [3] The star is rotating slowly, with a period that is most likely an integer multiple of 53 days. Gliese 1214 b, planet, semi-major axis: 0.0149±0.0003 AU New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. Gliese 1214 Facts. Gliese 1214 is not part of the constellation outline but is within the borders of the constellation. World's most comprehensive interactive database of extrasolar planets updated daily since 1995. Gliese 1214 b is a large exoplanet 42 light years from Earth, it is a giant terrestrial planet, with its surface theoretically totally covered by water, being an ocean planet. Scientists say Gliese 1214 b is likely water-rich. It is located at a distance of approximately 47 light years from Earth. [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. Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. 0.05%). intense fragrance in a compact package.

This planet is a super-Earth with a radius of 2.7 Earth radii and 6.5 Earth masses. 2 Millionen km). & SEAGER S. ApJ. For that reason, scientists have nicknamed the planet "the waterworld". Gliese 1214 là một sao lùn đỏ M4.5 trong chòm sao Xà Phu với cường độ rõ ràng là 14,7. › Larger image GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. [1] Given the planet's mass and radius, its density can be calculated. [3], No transit-time variations have yet been found for this transit. It is a real life planet that has its own wikipedia page here. Observed transit depths and theoretical models for GJ 1214 b Observed transit for GJ 1214 b The timeline series includes a compilation of artist's concepts depicting milestones from the Kepler mission-NASA's first mission capable of detecting Earth-size planets around sun-like stars. [11] The star is about one-fifth the radius of the Sun[12] with a surface temperature estimated to be 3000 K (2730 °C; 4940 °F). is perfect for sampling scents in the car. Gliese 1214 Facts. However, the world is inferior to earth gravity due to its low density. Although no clear signs were observed of water vapor or any other molecule, the authors of the study believe the planet may have an atmosphere composed mainly of water vapor. ApJ 773, 144; … [7] GJ 1214 b could be a rocky planet with an outgassed hydrogen-rich atmosphere, a mini-Neptune, or an ocean planet. Another possibility is that there may be a thick layer of high clouds, which absorbs the starlight. Gliese 1214 B è un brano popolare di Mirage | Crea i tuoi video TikTok col brano Gliese 1214 B ed esplora 0 video creati da altri autori sia nuovi che famosi. [1], In December 2013, NASA reported that clouds may have been detected in the atmosphere of GJ 1214 b. Tidal evolution of exo-planetary systems: WASP-50, GJ 1214 and CoRoT-7 2012 DONG Y. › Larger image GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. It is the home planet of the Bloboits. Follow-up radial-velocity measurements were then made with the HARPS spectrograph on the ESO's 3.6-meter telescope at La Silla, Chile; those measurements succeeded in providing independent evidence for the reality of the planet. Tag: Gliese 1214b. 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. It gives a quick overview of the hierarchical architecture. For that reason, scientists have nicknamed the planet "the waterworld". On Earth, the scale height is about 6 miles (10 kilometers), while on Gliese 1214 b it is three times deeper, according to Narita. The mass of the planet can be inferred from sensitive observations of the parent star's radial velocity, measured through small shifts in stellar spectral lines due to the Doppler effect. Gliese 1214 is mostly made out of 200 degree boiling water. & JIANG-HUI J. The parent star is 42 light-years from the Sun, in the constellation Ophiuchus where its sector name comes from.

Planet je dosada najbolji kandidat za oceanski planet, tj. [6], It is a super-Earth, meaning it is larger than Earth but is significantly smaller (in mass and radius) than the gas giants of the Solar System. [13], GJ 1214 b may be cooler than any other known transiting planet prior to the discovery of Kepler-16b in 2011 by the Kepler mission. [3] Although GJ 1214 has a low to moderate level of magnetic activity, it does undergo flares and is a source of X-ray emission with a base luminosity of 7.4×1025 erg s−1. Astronomers have claimed the existence of a new class of planet: a "water-world" with a thick, steamy atmosphere. Its luminosity is only 0.33% that of the Sun. GJ 1214b is located in the constellation Ophiuchus, some 40 light-years from us. GJ 1214 b, auch Gliese 1214 b, ist eine im Jahr 2009 entdeckte extrasolare Supererde. [7] If it is a waterworld, it could possibly be thought of as a bigger and hotter version of Jupiter's Galilean moon Europa. Prvi je i jedini otkriven planet u sustavu. 6:00. Science China Physics, Mechanics & … Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009.Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus.As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet. GJ 1214 B, also known as Gliese 1214 B, is an exoplanet that orbits the star GJ 1214. It is a super-Earth because it is larger than Earth but has a mass and radius significantly less than those of the ice giants in the Solar System. Notes AAS, 4, 231 paper Diverse outcomes of planet formation and composition around low-mass stars and brown dwarfs Gliese 1214 b is an exoplanet that orbits the red dwarf star Gliese 1214. A search for additional planets using transit timing variations was negative. However, the world is inferior to earth gravity due to its low density. A nearby alien planet six times the size of the Earth which is covered with a water-rich atmosphere that includes a strange "plasma form" of water. Gliese 1214 b is an exoplanet that orbits the star Gliese 1214. Gliese 1214 b is a planet 48 light-years away from Earth. Gliese 1214 b. Cosmic Speculation's Aureole diffuser . [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. A paper was then published in Nature announcing the planet and giving estimates of its mass, radius, and orbital parameters. [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. Nó nằm ở khoảng cách khoảng 47 năm ánh sáng từ Trái đất .
