Astron. [14], The 55 Cancri system is located fairly close to the Solar System: the Gaia astrometry satellite measured the parallax of 55 Cancri A as 79.4274 milliarcseconds, corresponding to a distance of 12.59 parsecs (41.06 light years). The red dwarf 55 Cancri B is of the 13th magnitude and only visible through a telescope. 2010 Since the planet was detected indirectly through observations of its star, properties such as its radius, composition and temperature are unknown. 2008 It has the Bayer designation Rho1 Cancri (ρ1 Cancri); 55 Cancri is the Flamsteed designation (abbreviated 55 Cnc). arxiv, Model of the Search For Extraterrestrial Intelligence with Coronagraphic Imaging paper, A Survey of Multiple Planet Systems 2008 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." In July 2014 the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars. & Astrophys., 532, A79 & Astrophys., 542, A92 [37] However, Dawson and Fabrycky (2010)[38] concluded that the 2.8 day planet was indeed an alias, as suggested by Wisdom (2005), and that the correct period was 0.7365 days. The message was named Cosmic Call 2; it was sent on July 6, 2003, and it will arrive at 55 Cancri in May 2044. SIMPSON E., BALIUNAS S., HENRY G. & WATSON C. & UNGER N. 2015 [39][40] The planet itself is not thought to be conducive to life, but hypothetical moons in principle could maintain at least microbial life. 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. PASJ 55 Cancri is a binary star system located 41[1] light-years away from the Sun in the zodiac constellation of Cancer. ENDL M., ROBERTSON P., COCHRAN W., MACQUEEN Ph., BRUGAMYER E. & 4 additional authors While 55 Cnc f had a mass about half that of Saturn and was surely a gas giant incapable of supporting life as we know it, any large moons it might possess could potentially be habitable. 2011 2010 Mech. 55 Cancri f is fourth in distance from 55 Cancri A of the known planets and orbits at 0.781 AU, inside the habitable zone of the star.

In 2005, Jack Wisdom combined three data sets and drew two distinct conclusions: that the 2.8 day planet was an alias and that there was a Neptune-scale planet with a period near 261 days.

MNRAS, 423, Issue 3, 2800-2814 2014 2018 2011 And as soon as the discovery of 55 Cnc f was officially announced, the claim was made that this was the first planet to be found in the habitable zone (HZ) of another star [2]. 2012 [35] 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. 2018 55 Cancri, Rho1 Cancri, HIP 43587, BD+28°1660, Gliese 324, HD 75732, HR 3522: Spectral Type: G8V: Mass: 0.9500 Solar Masses: Radius: 596,718.7804 Km 370,783.8598 Miles 0.8574 Solar Radii: Density: 2.1231 grams/cc: Rotation Period: 1,012.8000 Hours 42.2000 Days Temperature: 5,570.0000 K: Luminosity (bolometric): 0.6300: Luminosity (visual): 0.3238 2008 VOYATZIS G. confirmed the existence of the 260 day planet proposed in 2005 by Wisdom. ApJ., 701, 154 2012 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.

Letters, 698, L1 paper, A dynamical perspective on additional planets in 55 Cancri It orbits in the so-called "habitable zone," which means that liquid water could exist on the surface of a possible moon. Astrometric observations with the Hubble Space Telescope measured an inclination of 53° of the outer planet d,[35] though this result relies on the precise orbital parameters which have been substantially revised since this was published.
