글리제 876 b는 글리제 876계(系)에서 가장 바깥쪽을 도는 행성이기도 하다. There are three planets orbiting the star; Gliese 876 b has a mass 2.64 times that of Jupiter and is in the outer habitable zone, Gliese 876 c has a mass 0.78 times that of Jupiter & is in the inner habitable zone and Gliese 876 d has a mass between 5.88 and 8.41 times that of Earth and may be … Byla objevena v červnu 1998 jako první známá planeta obíhající červeného trpaslíka. Gliese 876 b Gliese 876 e. Poor Relationships. Gliese 876 b estas en orbita resonanco 1:2 kun la pli interna planedo Gliese 876 c, kio kaŭzas grandan gravitan interagon inter ambaŭ planedoj, kio provokas ke la orbitaj elementoj ŝanĝu tre rapide laŭ la orbitoj precesias. Ngôi sao này thuộc Chòm sao Aquarius, có 4 ngoại hành tinh quay quanh nó đó là Gliese 876 b, c, d và e. Để so sánh, khối lượng của Gliese 876 gấp 0,37 lần khối lượng Mặt Trời độ sáng của Gliese 876 gấp 0,012 lần độ sáng Mặt Trời. Later measurements reduced the value of the mutual inclination,[10] and in the latest four-planet models the incorporation mutual inclinations does not result in significant improvements relative to coplanar solutions. Byla objevena v červnu 1998 jako první známá planeta obíhající červeného trpaslíka. Gliese 876 is a star system located 4.70 parsecs from Earth. [citation needed]. Gliese 876 e This planetary system comes close to a triple conjunction between the three outer planets once per orbit of the outermost planet. With an estimated minimum mass only 5.88 times that of the Earth, it is possible that it is a dense terrestrial planet. The Tansaku-teki division of Hoshi Enterprises surveyed the Gliese 876 system in 2160 and found that metallicity levels were over twice that of Sol. [29], GJ 876 is a candidate parent system for the ʻOumuamua object. Gliese 876 b on eksoplaneetta ja todennäköinen kaasujättiläinen, joka löydettiin 23. kesäkuuta 1998. In 1998 an extrasolar planet was announced in orbit around Gliese 876 by two independent teams led by Geoffrey Marcy and Xavier Delfosse. [12], The planet orbits a (M-type) star named Gliese 876. Jump to navigation Jump to search. None. It is also the first extrasolar system around a normal star with measured coplanarity. It appears in the constellation Aquarius, the water bearer, near other stars in water-related constellations, like Cetus. Gliese 876 b-Wikipedia. Gliese 876:n planeetat [11], This planet, like c and e, has likely migrated inward. The star is an M3V spectral type, making it a Red Dwarf. [26] In 2018 a study using hundreds of new radial velocity measurements found no evidence for these planets. The Geneva team used telescopes at the Haute-Provence Observatory in France and the European Southern Observatory in La Serena, Chile. [30], Gliese 876 has a notable orbital arrangement. Được phát hiện vào tháng 6 năm 1998, Gliese 876 b là hành tinh đầu tiên được phát hiện quay quanh một sao lùn đỏ. La 23-an de junio 1998 estis anoncita la malkovro de planedo ĉirkaŭ Gliese 876 de du sendepandaj skipoj gviditaj de Geoffrey Marcy kaj Xavier Delfosse. It is in a 1:2 orbital resonance with the outermost known planet, taking 30.340 days to orbit the star. 91 Aquarii is an orange giant star orbited by one planet, 91 Aquarii b, a Super-Jupiter. Obrázky, zvuky či videa k tématu Gliese 876 b ve Wikimedia Commons; … [5] This type of variability is thought to be caused by large starspots moving in and out of view as the star rotates. It completes one orbit in approximately 61 days. [25], To support an Earth-like atmosphere for about 4.6 billion years (the age of the Earth), the moon would have to have a Mars-like density and at least a mass of 0.07 M⊕. Discovered in June 1998, Gliese 876 b was the first planet to be discovered orbiting a red dwarf. Gliese 876 elsendas X-radiadon. In comparison, the Sun is about 4.6 billion years old[13] and has a surface temperature of 5778 K.[14], Gliese 876 b is in a 1:2:4 Laplace resonance with the inner planet Gliese 876 c and the outer planet Gliese 876 e: in the time it takes planet e to complete one orbit, planet b completes two and planet c completes four. [6] Their analysis suggested that the orbital inclination is 84°±6° (close to edge-on). Gliese 876 b is an extrasolar planet orbiting the red dwarf star Gliese 876. Gliese 876, juga disebut IL Aquarii, adalah bintang katai merah sejauh 15 tahun cahaya di rasi bintang Aquarius.Pada tahun 2008, telah dikonfirmasi bahwa terdapat tiga planet luar surya yang mengorbit bintang ini.
