gliese 1214 b

Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. Due to the relatively small size of GJ 1214 b's parent star, it is feasible to perform spectroscopic observations during planetary transits. & JIANG-HUI J. It is a real life planet that has its own wikipedia page here. The indicator of gravity reaches 0.91 g, which resembles the situation on Venus. However, the world is inferior to earth gravity due to its low density. Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. For [14], Media related to GJ 1214 b at Wikimedia Commons, Coordinates: 17h 15m 18.94s, +4° 57′ 49.7″, "Open Exoplanet Catalogue – Gliese 1214 b", "Mass–radius relationships for solid exoplanets", "10 Real Planets That Are Stranger Than Science Fiction", "Release 13-383 – NASA's Hubble Sees Cloudy Super-Worlds With Chance for More Clouds", "Astronomers Find Super-Earth Using Amateur, Off-the-Shelf Technology", Astronomers Find World with Thick, Inhospitable Atmosphere and an Icy Heart. [7] GJ 1214 b could be a rocky planet with an outgassed hydrogen-rich atmosphere, a mini-Neptune, or an ocean planet. 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]. Riječ je o Superzemlji, ali samo po veličini. 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.

Gliese 1214 is not part of the constellation outline but is within the borders of the constellation. [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). Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus. [1][14], While very little is known about GJ 1214 b, there has been speculation as to its specific nature and composition. [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.

For that reason, scientists have nicknamed the planet "the waterworld". 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. 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. The planet orbits a small red dwarf star which has only 16% the mass of our own sun. Gliese 1214 is not part of the constellation outline but is within the borders of the constellation.

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. Although Gliese … [1] Given the planet's mass and radius, its density can be calculated. [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. They then observed the star more closely and confirmed that it dimmed by roughly 1.5% every 1.58 days. [7] Some of the solid-phase water could be in the form of ice VII.
