[3] It is located at a distance of approximately 47 light years from Earth. Artist’s impression of GJ 1214 b in transit.tif 3,445 × 2,584; 15 MB The planet was discovered in December 2009. [1], In December 2013, NASA reported that clouds may have been detected in the atmosphere of GJ 1214 b. Read Gliese 1214 B from the story A Mermaid's Tales (short stories) by Reading_Mermaid08 (The Reading Mermaid) with 49 reads. Gliese 1214 is a dim M4.5 red dwarf in the constellation Ophiuchus with an apparent magnitude of 14.7. Gliese 1214, stellar object 1.1. On Earth, the scale height is about 6 miles (10 kilometers), while on Gliese 1214 b it is three times deeper, according to Narita. [1], The radius of GJ 1214 b can be inferred from the amount of dimming seen when the planet crosses in front of its parent star as viewed from Earth. [8] It also shows a 1% intrinsic variability in the near-infrared probably caused by stellar spots. Astronomers have claimed the existence of a new class of planet: a "water-world" with a thick, steamy atmosphere. They then observed the star more closely and confirmed that it dimmed by roughly 1.5% every 1.58 days.

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. Discovered by the MEarth project and investigated further by the HARPS spectrograph on ESO’s 3.6-metre telescope at La Silla, GJ1214b is the second super-Earth exoplanet for which astronomers have determined the mass and radius, giving vital clues about its structure. Discovered in 2009, the planet is about 2.7 times Earth’s diameter and is almost 7 … "[13] The X-ray flux from the host star is estimated to have stripped 2–5.6 M⊕ from the planet over the lifetime of the system. Gliese 1214 Facts. 2. And here are some interesting facts about the planet GJ 1214 b 1. In early 2009, the astronomers running the project noticed that the star GJ 1214 appeared to show drops in brightness of that sort. Mediterranee: Bergamot, Bulgaria Rose ,Iris Or [7] GJ 1214 b is also significant because its parent star is relatively near the Sun and because it transits (crosses in front of) that parent star, which allows the planet's atmosphere to be studied using spectroscopic methods. [1][14], While very little is known about GJ 1214 b, there has been speculation as to its specific nature and composition. [12] Its luminosity is only 0.33% that of the Sun. Gliese 1214 is a m4.5 star that can be located in the constellation of Ophiuchus. Planet je dosada najbolji kandidat za oceanski planet, tj. planet koji se sastoji od jezgre i masivnog ocenana, uz planet Kepler-22b. 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. 1. This artist’s impression shows how the newly discovered super-Earth surrounding the nearby star GJ1214 may look. For It is located at a distance of approximately 47 light years from Earth. Riječ je o Superzemlji, ali samo po veličini. Featuring a fresh blend of lotus flower, bergamot and lemon leaf, this hand-poured candle in a ceramic cup delivers . 2012 BENNEKE B. [7] Because of the varying pressure at depth, models of a water world include "steam, liquid, superfluid, high-pressure ices, and plasma phases" of water. 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. Because a thick and cloud-free hydrogen-rich atmosphere would have produced detectable spectral features, such an atmosphere appears to be ruled out. 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 ranked 116,856 th in the world and 2 nd in The Order of Black Knights for Most Extreme, scoring 14.47 on the Paul-Nader Subjective Decentrality Index. Gliese 1214b je egzoplanet koji kruži oko ultralakog crvenog patuljka Gliesea 1214 na udaljenosti od 47 svjetlosnih godina. GJ 1214 B, also known as Gliese 1214 B, is an exoplanet that orbits the star GJ 1214. As of 2015, GJ 1214 b is the most likely known candidate for being an ocean planet. However, the world is inferior to earth gravity due to its low density. An Upper Limit on the Extended Helium Atmosphere of GJ 1214 b 2020 PETIT dit de la ROCHE D., van den ANCKER M. & MILES-PAEZ P. Res. ApJ 773, 144; … is perfect for sampling scents in the car. 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. Riječ je o Superzemlji, ali samo po veličini. A search for additional planets using transit timing variations was negative. It’s a super-Earth, intermediate in size between Earth and Neptune. It is located at a distance of approximately 47 light years from Earth. Gliese 1214 b is an exoplanet that orbits the star Gliese 1214. The planet was discovered in December 2009. [7] If it is a waterworld, it could possibly be thought of as a bigger and hotter version of Jupiter's Galilean moon Europa. Science China Physics, Mechanics & … Prvi je i jedini otkriven planet u sustavu. [7] It is possible to propose structures by assuming different compositions, guided by scenarios for the formation and evolution of the planet. It is probably at least three billion years old and a member of the old disk. [12], The estimate for the stellar radius is 15% larger than predicted by theoretical models. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. The indicator of gravity reaches 0.91 g, which resembles the situation on Venus. Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. 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. The parent star is 42 light-years from the Sun, in the constellation Ophiuchus where its sector name comes from. However, the world is inferior to earth gravity due to its low density. planet koji se sastoji od jezgre i masivnog ocenana, uz planet Kepler-22b. Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus. It is also the first super-Earth around which an atmosphere has been found. em 16 de dezembro de 2009. While Gliese 1214 b is six times as large as earth, it is less than three times in width to be as big as a planet in between the size of Earth and Neptune. Astronomy Science ~ GJ 1214 b is a Super-Earth planet orbiting GJ 1214. Because of the estimated old age of the planetary system and the calculated hydrodynamic escape rate of 9×105 kg s−1, scientists conclude that there has been a significant atmospheric loss during the lifetime of the planet and any current atmosphere cannot be primordial. Elle est située à environ 40 années-lumière du Soleil. 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. On the weight of Gliese, 1214 b is 6.55 times the Earth's, and 2.5 times more in diameter. [7] Some of the solid-phase water could be in the form of ice VII. But the world has prepared a lot of surprises.

[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. A paper was then published in Nature announcing the planet and giving estimates of its mass, radius, and orbital parameters. Like other ocean planets, it has a surface that is extremely sensitive to the touch of anything, especially asteroids, which means it hates them.

The temperature of the stellar corona is estimated to be about 3.5×106 K.[10], In mid-December 2009, a team of Harvard-Smithsonian astronomers announced the discovery of a companion extrasolar planet, Gliese 1214 b, potentially composed largely of water and having the mass and diameter of a super-Earth. Comparative dimensions of Gliese 1214 b. Like other ocean planets, it has a surface that is extremely sensitive to the touch of anything, especially asteroids, which means it hates them. By comparing the observed spectrum before and during transits, the spectrum of the planetary atmosphere can be inferred.
