Discovery. Researchers estimated the surface temperature of 55 Cancri e could be as high as 4,892 F (2,700 C). Its mass is 8.08 Earths, it takes 0.7 days to complete one orbit of its star, and is 0.01544 AU from its star. Given hypothetical planet g of up to 50 Earth masses, stable mean motion resonance regions lie at 3f:2g, 2g:1d, and 3g:2d. This table lists all planets in the system 55 Cancri. confirmed the existence of the 260 day planet proposed in 2005 by Wisdom. 55 Cancri e is a super-Earth exoplanet that orbits a G-type star similar to our Sun. The red dwarf 55 Cancri B is of the 13th magnitude and only visible through a telescope. 55 Cancri (55 Cnc) també és anomenada Rho cancri, segons la seva denominació de Bayer. Measurements of the star suggested that this was close to the star's rotation period, which raised the possibility that the 43-day signal was caused by stellar activity. In 1997, the discovery of a 51 Pegasi-like planet orbiting 55 Cancri A was announced, together with the planet of Tau Boötis and the inner planet of Upsilon Andromedae. Despite their wide separation, the two stars appear to be gravitationally bound, as they share a common proper motion. 55 Cancri A má zdánlivou hvězdnou velikost 5,95 a je viditelná pouhým okem za velmi tmavé oblohy. , A hypothesis for the high metal content in SMR dwarf stars is that material enriched in heavy elements fell into the atmosphere from a protoplanetary disk. 55 Cancri f, also referred to as Rho 1 Cancri f, is an extrasolar planet approximately 41 light-years away from Earth in the constellation of Cancer (the Crab). 55 Cancri f, estas ekstersunsistema planedo je proksimume 41 lumjarojn for de la Tero en la konstelacio Kankro.  (The IAU originally announced the winning name was Lippershey for 55 Cancri d. In January 2016, in recognition that his actual name was Lipperhey (with Lippershey an error introduced in the 19th century), the exoplanet name was corrected to Lipperhey by the IAU and that name was submitted to the official sites that keep track of astronomical information. Pat Brennan  With 8.3 Earth masses, it is a large super-Earth which was originally thought to have an orbital period of 2.8 days, though it was later found that this was an alias of its true period of 0.74 days by observations of e transiting in 2011. Its mass is 0.141 Jupiters, it takes 262 days to complete one orbit of its star, and is 0.788 AU from its star. As for the space outside d's orbit, its stability zone begins beyond 10 AU, though there is a stability zone between 8.6 – 9 AU due to a 2:1 resonance. Nota: el anillo y el satélite alrededor de 55 Cacri f son ficticios.  Under the rules for naming objects in binary star systems it should be named 55 Cancri Ab and this more formal form is occasionally used to avoid confusion with the secondary star 55 Cancri B.

They honor the astronomers Nicolaus Copernicus, Galileo Galilei, Tycho Brahe and Thomas Harriot and the spectacle makers and telescope pioneers Hans Lipperhey and Jacharias Janssen. Age estimates for 55 Cancri A include 7.4–8.7 billion years and 10.2 ± 2.5 billion years. This limits the total mass of fine dust around the star to less than 0.01% of the Earth's mass.  55 Cancri A also has more carbon than the Sun, with a C/O ratio of 0.78, compared to solar value of 0.55. 55 Cancri B, stellar object. These radial velocity measurements still showed a drift unaccounted-for by this planet, which could be explained by the gravitational influence of a more distant object. 55 Cancri is a binary star system located 41 light-years away from the Sun in the zodiac constellation of Cancer. , Observations of 55 Cancri A in the submillimeter region of the spectrum have thus far failed to detect any associated dust. 55 Cancri E, discovered in 2004, has a mass 8.3 times the mass of Earth and an orbital period of 0.74 days. ), In 2016, the IAU organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. , "Addressing confusion in double star nomenclature: The Washington Multiplicity Catalog", NameExoWorlds: An IAU Worldwide Contest to Name Exoplanets and their Host Stars, Final Results of NameExoWorlds Public Vote Released, "Bulletin of the IAU Working Group on Star Names, No.  The planet was discovered by measuring the star's radial velocity, which showed a periodicity of around 14.7 days corresponding to a planet at least 78% of the mass of Jupiter. Anya Biferno.  The first planet discovered orbiting 55 Cancri A was designated HR 3522b by its discoverers, though it is more commonly referred to as 55 Cancri b. 55 Cancri f is a gas giant exoplanet that orbits a K-type star.  It is more enriched than the Sun in elements heavier than helium, with 186% the solar abundance of iron; it is therefore classified as a rare "super metal-rich" (SMR) star. The multiplanet 55 Cancri system is located about 40 light-years away from Earth. (2004), and a 260-day Neptune-sized planet, as first reported by Wisdom (2005). 55 Cancri, also known as Rho Cancri, is a binary star system located 41 light years away in the constellation of Cancer and is best known for having five extrasolar planets (as of 2007), including possibly one terrestrial, rocky, "super-Earth". 55 Cancri A is visible to the unaided eye only under very dark, clear conditions with an apparent magnitude of 5.95.
