Distance to Gliese 1214. Located at 42.4 light-years away in the Ophiuchus constellation. New Hubble observations confirm that GJ 1214b is most likely enveloped in a steamy, superheated atmosphere. But the world has prepared a lot of surprises. The planet has a mass and radius of 6.5 and 2.7 times that of Earth, respectively. 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. GJ 1214 b is a “super-Earth,” a planet that’s bigger than Earth but likely still solid and terrestrial, rather than a gas giant. Comparative dimensions of Gliese 1214 b. GJ 1214 B, also known as Gliese 1214 B, is an exoplanet that orbits the star GJ 1214. Gliese 1214 b; Alternative planet names: GJ 1214 b, Gj 1214 b, Gl 1214 b, Gaia DR2 4393265392167891712 b: Description: Gliese 1214 is a red dwarf in the constellation Ophiuchus only 40 light years away. And here are some interesting facts about the planet GJ 1214 b 1.GJ 1214b, also known as Gliese 1214b and within 42 light years from Earth and was discovered in November 2009. Gliese 1214 b is an exoplanet that orbits the star Gliese 1214. The indicator of gravity reaches 0.91 g, which resembles the situation on Venus. Its equilibrium temperature could be between approximately 120–282°C, depending on how much of the star's radiation is reflected back into space.>> The planet was found with a 40cm telescope and commercially available cameras. This planet is a super-Earth with a radius of 2.7 Earth radii and 6.5 Earth masses. 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. The proximity of Gliese 1214 b to its star is the reason water may exist as plasma over there.

The Parallax of the star is given as 69.04000 which gives a calculated distance to Gliese 1214 of 47.24 light years from the Earth or 14.48 … This artist’s impression shows how the newly discovered super-Earth surrounding the nearby star GJ1214 may look. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. On the weight of Gliese, 1214 b is 6.55 times the Earth's, and 2.5 times more in diameter. Parent star; Star: GJ 1214: Constellation: Ophiuchus: Right ascension (α) 17 h 15 m 18.942 s: Declination (δ) +04° 57′ 49.69″ Apparent magnitude (m V) 14.71 ± 0.03: Distance On December 1, 2010, a team of astronomers announced the results of the first analysis of the atmosphere of a super-Earth planet, GJ 1214 b, using the European Southern Observatory's Very … This super-Earth, also known as Gliese 1214b, orbits a red-dwarf star every 38 hours at a distance of 1.3 million miles, giving it an estimated temperature of 450 degrees Fahrenheit. However, the world is inferior to earth gravity due to its low density. The actual color of GJ 1214 b is not known yet. Detailed information on planet GJ 143 b orbiting around star GJ 143. It is 6.36 times the mass of Earth and its radius is 2.69 times Earth’s. Multi-Color Transit Photometry of GJ 1214b through BJHKs-Bands and a Long-Term Monitoring of the Stellar Variability of GJ 1214 2013 NARITA N., FUKUI A., IKOMA M., HORI Y., KUROSAKI K. & 17 additional authors ApJ, 773, 144 paper arxiv Star temperature: 3026: Wikipedia article: GJ 1214 b: Back : Fictional info ; Suggested name: Mipo Byatsu: Planet type: Small hot gas planet: This small hot gas planet is named after the deity Mipo Byatsu, the creator of the sky. An artist’s rendition of Gliese 1214 b traveling in front of its star, shown in blue light (Credit: NAOJ) (via GJ 1214 b; Exoplanet: List of exoplanets: 300px Size comparison of GJ 1214 b with Earth (left) and Neptune (right). “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. The star's modest surface temperature of 2,700°C, though, means that GJ 1214 b itself is a balmy 200°C. Posted by Will Baird at 4:00 PM. Gliese 1214b orbits Gliese 1214 at a distance of 0.0140 Astronomical Units and completes one full orbit every 38 hours. Like other ocean planets, it has a surface that is extremely sensitive to the touch of anything, especially asteroids, which means it hates them. Ever since its discovery in 2009, an exoplanet orbiting a nearby, red-dwarf star has attracted lots of attention from astronomers. We estimate that GJ 1214 b evaporates at a rate of 1.3E10 g/s and has lost a total of ~2-5.6 MEarth. The planet was discovered in December 2009. GJ 1214 b - is circling dim host red dwarf star GJ1214 every 38 hours at a distance of just 1.01967 x 10^10 meters (0.06816±0.0019 AU). There’s a few known planets that could be ocean worlds, but today we’re looking at a single one: GJ 1214 b, orbiting a red dwarf within the Sun’s local neighborhood. World's most comprehensive interactive database of extrasolar planets updated daily since 1995. 42 light years away from Earth there is the planet GJ 1214 b orbiting a red dwarf. › Larger image GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. GJ 1214b, also known as Gliese 1214b, is 42 light years from Earth and was discovered in November 2009. Being larger than Earth and the other terrestrial planets yet smaller than the ice giants of our solar system, Neptune and Uranus, it is characterized as a Super Earth. The planet orbits a small red dwarf star which has only 16% the mass of our own sun. This planet is one of the well-known super-Earths discovered by Charbonneau, (2009) in the MEarth Project, which focuses on finding habitable planets around nearby small stars. Further, we determine a coronal temperature of about -3.5 MK, which is typical for coronal emission of moderately active low-mass stars. Astronomy Science ~ GJ 1214 b is a Super-Earth planet orbiting GJ 1214. The planet, GJ 1214 b, has an atmosphere that is either dominated by steam or covered by thick clouds or hazes . "As the temperature and pressure are so high, water is not in a usual form (vapor, liquid, or solid), but in an ionic or plasma form at the bottom the atmosphere — namely the interior — of Gliese 1214 b," principle investigator Norio Narita of the National Astronomical Observatory of Japan told by email. Based on the star's spectral, the stars temperature is between 2,400.00 and 3,700.00 degrees kelvin. 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. Plasma water is considered one of the supercritical forms of water we mentioned earlier. GJ 1214b is classified as a water-world, and is the only example of such a planet yet to be discovered. The parent star is 42 light-years from the Sun, in the constellation Ophiuchus where its sector name comes from. ... GJ 1214 b, strongly suggest that 2-10 M(earths) planets rather prefer to – Gliese 581 g is even closer an Earth analog than the ESI suggests, since it is so sensitive to temperature. Astronomers using the Hubble Space Telescope have discovered a new class of alien planets, so-called steamy waterworlds. The extremely high temperature from the star and the high pressure of the planet causes water to heat and compress so much that it becomes plasma. GJ 1214 b is located in the constellation Ophiuchus, northwest of the center of our Milky Way galaxy.
