The planet 55 cancri e is the girls best friend because 55 cacnri e is actually just a diamond out in space orbiting a star. When 55 cancri e was formed it was comprised completely of carbon, thanks to its intense pressure and heat through its parent star. 55 cancri e compressed into a massive unpolished diamond this planet is so huge that it is valued incomprehensible $26.9 nonillion which is only about 3840,000,000,000,000,000x quintillion times the earth's GDP, but Before you set out for this diamond planet with a drill. 55 cancri e is located over 40 light years away from earth and if you were somehow able to bring all the diamonds back with you the sheer amount diamond you would collect from the planet will crash the earths diamond market instantly making your diamonds completely worthless.
55 Cancri e also named Janssen, is an exoplanet closely orbiting its Sun-like host star55 cancri A. The mass of the exoplanet is about 8.63 Earth masses and its diameter is about twice that of the Earth,thus classifying it as the first super earth discovered around a main sequence star, predating Gliese 876 b by a year. It takes fewer than 18 hours to complete an orbit and is the innermost known planet in its planetary system. 55 Cancri e was discovered on 30 August 2004. However, until the 2010 observations and recalculations, this planet had been thought to take about 2.8 days to orbit the star. In October 2012, it was announced that 55 Cancri e could be a carbon planet.
In July 2014 international astronomical union launched a process for giving proper names to certain exoplanets and their host stars.The process involved public nomination and voting for the new names. In December 2015, the IAU announced the winning name was Janssen for this planet.The winning name was submitted by the Royal Netherlands Association for Meteorology and Astronomy of the Netherlands It honors the spectacle maker and telescope pioneer Zacharias Janssen.
In February 2016, it was announced that NASA's Hubble space telescope had detected hydrogen and helium (and suggestions of hydrogen cyanide), but no water vapor, in the atmosphere of 55 Cancri e, the first time the atmosphere of a super earth exoplanet was analyzed successfully.
