55 Cancri e is a super-Earth — about twice our planet’s size — that zooms around its star in 18 days. 55 Cancri c, planet, semi-major axis: 0.2373 ±0.0013 AU. 55 Cancri c (abreviado 55 CNC c) é un planeta extrasolar cunha órbita excéntrica ó redor da estrela 55 Cancri A (que é semellante ó noso Sol), completando unha órbita cada 44,34 días. 55 Cancri e, planet, semi-major axis: 0.0154 ±0.0001 AU. 55 Cancri e's high level of temperature contributes to "supercritical" liquid state Follow-up observations with the Spitzer Space Telescope in 2012 show that this planet is weirder than expected. 55 Cancri is a binary star system located 41 light-years away from the Sun in the zodiac constellation of Cancer.It has the Bayer designation Rho 1 Cancri (ρ 1 Cancri); 55 Cancri is the Flamsteed designation (abbreviated 55 Cnc). 55 Cancri c (abbreviated 55 Cnc c) is an extrasolar planet in an eccentric orbit around the Sun-like star 55 Cancri A, making one revolution every 44.34 days. 55 Cancri c (viết tắt là 55 Cnc c), có tên riêng chính thức là Brahe (pronounced / ˈ b r ɑː h iː / or / ˈ b r ɑː /), là một hành tinh ngoài hệ mặt trời có quỹ đạo lệch tâm quay xung quanh ngôi sao giống như Mặt trời 55 Cancri A, thực hiện một chu kì quỹ đạo cứ sau 44,34 ngày. 55 Cancri c was discovered on June 13, 2002 and has a mass roughly half of Saturn. Its discovery was announced in … Its mass is 0.1714 Jupiters, it takes 44.4 days to complete one orbit of its star, and is 0.241376 AU from its star. 55 Cancri c is a gas giant exoplanet that orbits a K-type star. 55 was believed to be a lava flux on the surface of Cancri e. 55 Cancri e is close to its star. É o terceiro planeta coñecido en orde de distancia respecto da súa estrela. Mass: The radial velocity method used to discover 55 Cancri e obtains the minimum weight of 7.8 times that of Earth or 48% of Neptune mass. For a while, it was dubbed the “diamond planet” because scientists suggested that it was composed of diamonds and graphite. 55 Cancri c foi descuberto o 13 de xuño de 2002 e ten unha masa de case a metade da de Saturno 55 Cancri d, planet, semi-major axis: 5.96 ±0.07 AU. It has a surface temperature of nearly 4,900 degrees Fahrenheit (2,700 degrees Celsius). The system consists of a K-type star (designated 55 Cancri A, also named Copernicus / k oʊ ˈ p ɜːr n ɪ k ə s /) and a smaller red dwarf (55 Cancri B). ... 55 Cancri e is a super-Earth which appears to exhibit extreme variations in brightness temperature. Capture of the 55 Cancri planets b and c into a 3:1 orbital resonance by migration 2005 SCHOLL H., MARZARI F. & TRICARICO P. BAAS, 37 no 2, 28.06 55 Cancri e orbits its parent star at a distance of 0.015 AU – about 25 times closer than Mercury is to our Sun – every 18 hours. On the dayside, temperatures on 55 Cancri e can reach about 4,400 degrees Fahrenheit (2,427 degrees Celsius). Infrared mapping with the Spitzer Space Telescope indicated an average front-side temperature of 2,573 K (2,300 °C; 4,172 °F) and an average back-side temperature of approximately 1,371 °C. It is the third known planet in order of distance from its star. lació de Càncer, a estimadament 40,9 anys-llum de distància a la Terra.Forma part d'un sistema planetari, amb cinc planetes detectats fins ara. 55 Cancri e is tidally locked, meaning it always keeps the same face pointed at its star.
