However, the world is inferior to earth gravity due to its low density. GJ 1214b is classified as a water-world, and is the only example of such a planet yet to be discovered. Astronomy Science ~ GJ 1214 b is a Super-Earth planet orbiting GJ 1214. Contents[show] Name GJ 1214 Orbiter GJ 1214 b Characteristics Mass = 0.157 Solar mass Radius = 0.211 Solar radius Effective temperature = 3026 K Age = 6 billion years About the star Red dwarf star. 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 The star's modest surface temperature of 2,700°C, though, means that GJ 1214 b itself is a balmy 200°C. 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. Its equilibrium temperature could be between approximately 120–282°C, depending on how much of the star's radiation is reflected back into space.>> New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. Located at 42.4 light-years away in the Ophiuchus constellation. GJ 1214 b is located in the constellation Ophiuchus, northwest of the center of our Milky Way galaxy. The planet was found with a 40cm telescope and commercially available cameras. Based on the star's spectral, the stars temperature is between 2,400.00 and 3,700.00 degrees kelvin.

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 581 g is even closer an Earth analog than the ESI suggests, since it is so sensitive to temperature. GJ 1214b, also known as Gliese 1214b, is 42 light years from Earth and was discovered in November 2009. Gliese 1214b orbits Gliese 1214 at a distance of 0.0140 Astronomical Units and completes one full orbit every 38 hours. "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. But the world has prepared a lot of surprises. 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). 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. Distance to Gliese 1214.

New Hubble observations confirm that GJ 1214b is most likely enveloped in a steamy, superheated atmosphere. ... GJ 1214 b, strongly suggest that 2-10 M(earths) planets rather prefer to The planet orbits a small red dwarf star which has only 16% the mass of our own sun. › Larger image GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. This artist’s impression shows how the newly discovered super-Earth surrounding the nearby star GJ1214 may look.
