Gliese 876 b is an exoplanet orbiting the red dwarf Gliese 876. It completes one orbit in approximately 61 days. Discovered in June 1998, Gliese 876 b was the first planet to be discovered orbiting a red dwarf.
The first announcement of a planet around the star was Gliese 581b discovered by astronomers at the Observatory of Geneva in Switzerland and Grenoble University in France. Detected in August 2005 and using extensive data from the ESO/HARPS spectrometer it was the fifth planet to be discovered around a red dwarf. [5]
The first extrasolar planet found to have a density compatible with being a rocky planet is CoRoT-7b in 2009. 55 Cancri e was found to be a terrestrial planet in 2011. First super-Earth orbiting a main sequence star [NB 2] Gliese 876 d: Gliese 876: 2005 Orbits a red dwarf star. First icy extrasolar planet orbiting a main sequence star OGLE-2005 ...
Red dwarf: This red dwarf has a size comparable to that of the planet Saturn. As of 2019, it is the second lightest hydrogen-fusing star known, marginally heavier (0.0777-0.0852M ☉) than the 2MASS J0523-1403. Although its mass is comparable to that of TRAPPIST-1, its radius is 1/3 smaller. [63] [64] [65] Luhman 16 A 60,768 Brown dwarf
2M1207 b: The first planet found around a brown dwarf. The planet is also the first to be directly imaged (in infrared). According to an early estimate, it has a mass 5 times that of Jupiter; other estimates give slightly lower masses. It was originally estimated to orbit at 55 AU from the brown dwarf. The brown dwarf is only 25 times as ...
Quihua’s dwarf geckos are considered “small,” measuring about 2.5 inches in length, the study said. They have “cone-shaped” heads with “bronze” eyes. Their limbs are “short” and ...
Twelve exoplanet systems have been found in Aquarius as of 2013. Gliese 876, one of the nearest stars to Earth at a distance of 15 light-years, [19] was the first red dwarf star to be found to possess a planetary system. It is orbited by four planets, including one terrestrial planet 6.6 times the mass of Earth. The planets vary in orbital ...
