ApJ., 740, 49 , The winning names were those submitted by the Royal Netherlands Association for Meteorology and Astronomy of the Netherlands. This limits the total mass of fine dust around the star to less than 0.01% of the Earth's mass. The star 55 Cancri, only 40 light-years distant, is visible with binoculars towards the constellation of Cancer. ENDL M., ROBERTSON P., COCHRAN W., MACQUEEN Ph., BRUGAMYER E. & 4 additional authors XXI. Because of the planet's proximity to the star, it is tidally locked by gravity just as our moon is to Earth. 55-Cancri The aim of our study is to explore the possible existence of Earth-mass planets in the habitable zone of 55~Cancri, an effort pursued based on detailed orbital stability simulations.

The message was named Cosmic Call 2; it was sent on July 6, 2003, and it will arrive at 55 Cancri in May 2044. Fogg Martyn 55 Cancri b (abbreviated as "55 Cnc b"), and sometimes designated as 55 Cancri Ab, is an extrasolar planet orbiting the Sun-like star 55 Cancri A. The planet itself is estimated to be at least 44 Earth masses (possibly 57 Earth masses), meaning it is a smaller Neptune-like gas giant.  (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. 2008 , 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. The Diamond Planet is formally known as '55 Cancri e.' According to Reuters , it orbits a star in the constellation of Cancer and completes a rotation that takes Earth about 365 days in 18 hours. It reveals hot storms similar in intensity to those of Jupiter. ), In 2016, the IAU organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. 2012 PANOV K. 2008 Astron. 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 … A Possible 2:1 Resonance in the Exoplanetary Triple System HD 37124 arxiv, Abundance Stratification of Exoplanet Host Stars Astron. arxiv, Elemental ratios in stars vs planets , More planets are possible within the stable zone, between f and d at 0.9 to 3.8 AU with eccentricities below 0.4. 55 Cancri e is one of five planets encircling a sun-like star called 55 Cancri, which lies about 40 light-years from Earth in the constellation of Cancer. 2012 KAIB N., RAYMOND S. & DUNCAN M. 2014 HAGHIGHIPOUR N. & Astrophys., 619, A1 The star has only low emission from its chromosphere, and is not variable in the visible spectrum; but it is variable in X-rays.

In December 2015, the IAU announced the winning names were Copernicus for 55 Cancri A and Galileo, Brahe, Lipperhey, Janssen and Harriot for its planets (b, c, d, e and f, respectively). Fischer et al. 2014 The planet is a good example of a Hot Jupiter. 2018 & Astrophys., 530, A73 55 Cancri e is the closest exoplanet to it's star 55 Cancri e is also known as Janssen 55 Cancri e is made of diamonds and because of this , he is known as a "Carbon Planet."

These are some sketch redesigns I did for the life of an habitable moon orbiting the planet 55 Cancri F which exist on the habitable zone of its star, in this moon life didn't evolve naturally but was brought by a very old civilization around 270 millions of years before mankind in an attempt of a terraforming process. arxiv, The LCES HIRES/Keck Precision Radial Velocity Exoplanet Survey arxiv. paper, Planets and Debris Disks: Results from a Spitzer/MIPS Search for Infrared Excess 0.

KASHYAP V., DRAKE J. That means one side of 55 Cancri, referred to as the day side, is always cooking under the intense heat of its star, while the night side remains in the dark and is much cooler. ZHANG H. & ZHOU J.-L. paper, On the Ages of Planetary Systems with Mean Motion Resonances  An attempt to measure the spin-orbit misalignment of the innermost planet reported that it was in a nearly polar orbit, but this interpretation of the data has since been challenged by a subsequent study, with noted inconsistencies between the implied and measured stellar rotation. paper arxiv ADS, Feasibility of spectro-polarimetric characterization of exoplanetary atmospheres with direct observing instruments ApJ, 759, 19 BUTLER P., MARCY G., WILLIAMS E., HAUSER H. & SHIRTS P. & PISKUNOV N. 2011 2016 , The approximate ratios of periods of adjacent orbits are (proceeding outward): 1:20, 1:3, 1:6, 1:20. & SAAR S.

NELSON B., FORD E., WRIGHT J., FISCHER D., von BRAUN K. et al. It also bears the Bayer designation ρ¹ Cancri (Latinised to Rho¹ Cancri) and the Bright Star Catalogue designation HR 3522. After making further radial velocity measurements, a planet orbiting at a distance of around 5 AU was announced in 2002. , The 55 Cancri system was the first known to have four, and later five planets, and may possibly have more. 2008 MNRAS, 406, 1918  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.
