Around 16 Cygni B, one of the two Sun like yellow dwarves of the system 16 Cygni, orbits a giant planet, 16 Cygni … At the time, it had the highest orbital eccentricity of any known extrasolar planet. 16 Cygni system Edit b Edit. As a matter of fact the ship belongs to the Orion's Arm Fleet, an organisation which groups different races living relatively closed to the Solar system on the Milky Way's spiral arm named Orion's Arm.

Elle est située à envion 50,5 années-lumières ( 21,6 pc ) du Système solaire , dans la constellation du Cygne . La dernière modification de cette page a été faite le 11 novembre 2010 à 00:15. Stellar binary 1.1. It gives a quick overview of the hierarchical architecture. [1] This would make the body a true planet. While the mass of this object is well within the range expected for planets, the large orbital eccentricity cannot be explained simply by the standard model of growth of planets in a protostellar disk. (2000) claim a preliminary mass of 14 M J and inclination of 173.0 o Visual binary. At the time, it had the highest orbital eccentricity of any known extrasolar planet. 16 Cygni Bb, also discovered in 1996, has an extremely eccentric orbit that spends only part of its time in the CHZ, such an orbit would causes extreme seasonal effects. If you can improve it further, please do so. The eccentric orbit and mass of 16 Cygni Bb makes it extremely unlikely that a terrestrial sized planet will be found orbiting within the star's habitable zone. Localisation dans la constellation : Cygne. At the time, it had the highest orbital eccentricity of any known planet. As the inclination of the orbit cannot be directly measured and as no dynamic model of the system was then published, only a lower limit on the mass could then be determined. Discovery method Disc. 16 Cygni B has 1 planet: 16 Cygni B B, discovered in 1996, has a mass 534 times the mass of Earth and an orbital period of 799.5 days. An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age.. Times on this list are measured from the moment of the Big Bang. L'excentricité de l'orbite de la planète Yoyo provoquerait d'extrêmes saisons. English: Orbit diagram for the planet en:16 Cygni Bb. At the time, it had the highest orbital eccentricity of any known extrasolar planet. Thorough characterisation of the 16 Cygni system. 16 Cygni Bb. [3] It orbits its star once every 799 days and was the first eccentric Jupiter and planet in a double star system to be discovered. Its host star is located in the constellation of The Swan. 1996 68.99 1.04 5750 23 Librae b: 1.61 258.18 0.81 radial vel. Lorsque le Yoyo spatial a franchi la zone d'habitabilité et se rapproche de l'étoile B, le réchauffement est tel que le satellite serait balayé par des cyclones et d'effroyables tempêtes. 16 Cygni (of 16 Cyg) is ’n driedubbele ster sowat 69 ligjare van die Aarde af in die sterrebeeld Swaan.Dit bestaan uit twee Sonagtige geel dwergsterre, 16 Cygni A en 16 Cygni B, en ’n rooi dwerg, 16 Cygni C.In 1996 is ’n eksoplaneet ontdek in ’n sonderlinge wentelbaan om ster B. . 16 Cygni B 16 Cygni C 16 Cygni B b General Characteristics: Mass: 533.954 Earth mass[1] Semi-major axis: 1.68 AU[1] Eccentricity: 0.689[1] Orbital period: 799.5 Earth days[1] Discovery Information: Discovery date: *October 22, 1996[2] Discoverer(s): *Cochran[2] Detection method: Radial velocity[2] 16 Cygni B b 16 Cygni B b is likely to be a gas giant. 60 years have passed since the events on Alph, a medieval world located on a moon of 16 Cygni Bb, an exoplanet located about 70 light years from Earth.

At the time, it had the highest orbital eccentricity of any known planet. 16 Cygni or 16 Cyg is the Flamsteed designation of a triple star system approximately 69 light-years away from Earth in the constellation of Cygnus. It consists of two Sun-like stars, 16 Cygni A, and 16 Cygni B, complete with an red dwarf star, 16 Cygni C. An extrasolar planet was discovered around 16 Cygni B. While the mass of this object is well within the range expected for planets, the large orbital eccentricity cannot be explained simply by the standard model of growth of planets in a protostellar disk.

Plavalova and N.A. Mass: 2.38 ± 0.04 MJ Semimajor Axis: 1.693 Orbital period: 799.5 earth days Eccentricity: 0.689 ± 0.011 Planets Edit. 26 Cygni is a giant star that can be located in the constellation of Cygnus. Le satellite changerait brutalement de couleur passant d'une texture terrestre à une texture totalement désertique ! Un article de Wikipédia, l'encyclopédie libre. Assuming that 16 Cygni B has a mass of 1.0 the mass function then implies a mass for theM _ companion of 1.5/sin i Jupiter masses. Au plus proche de l'étoile, il fait plus de 450 °C ! 1. The star and the … It makes one revolution every 799 days and was the first eccentric Jupiter to be discovered. Les océans ne pourraient plus supporter la chaleur et s'évaporerait sous la forme d'épais nuages d'incendies en bouillant comme de l'eau dans une casserole. In October 1996 the discovery of a planetary -mass companion to the star 16 Cygni B was announced, with a mass at least 1.68 times that of Jupiter (MJ). Cependant, du fait de la forte excentricité orbitale de la géante gazeuse, la présence de vie dans la région est hautement improbable car les écarts de températures seraient trop importants au cours de la révolution de la planète[4].
