Er ist knapp 50 Lichtjahre von der Erde entfernt und umkreist in 38 Stunden im Sternbild Schlangenträger den roten Zwerg GJ 1214, dessen Strahlung 200 Mal schwächer ist als diejenige der Sonne. [1] The loss of primordial atmosphere was indirectly confirmed in 2020 as no helium was detected at Gliese 1214 b. › Larger image GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. 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. & SEAGER S. ApJ. [8] It also shows a 1% intrinsic variability in the near-infrared probably caused by stellar spots. 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. Using the fraction of Gliese 1214b’s luminosity to the Sun’s luminosity, I calculated these boundaries. [7] GJ 1214 b could be a rocky planet with an outgassed hydrogen-rich atmosphere, a mini-Neptune, or an ocean planet. Part 1 of 2.

Based on the spectral type (M4.5) of the star, the star's colour is red . [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. The discovery of a menagerie of exoplanets sized greater than Earth and smaller than Neptune has changed thinking about planets and solar systems. World's most comprehensive interactive database of extrasolar planets updated daily since 1995.

[1], In December 2013, NASA reported that clouds may have been detected in the atmosphere of GJ 1214 b. Gliese 1214, stellar object 1.1. Because a thick and cloud-free hydrogen-rich atmosphere would have produced detectable spectral features, such an atmosphere appears to be ruled out. 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. A paper was then published in Nature announcing the planet and giving estimates of its mass, radius, and orbital parameters. [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.
