What is 55 Cancri e?
'''55 Cancri e''' is a [[superterran]] exoplanet made almost entirely of [[carbon]], giving it the nickname the ''diamond planet'' or ''Lucy'' (from the [[Beatles]] song ''Lucy in the sky with diamonds''). The planet orbits a [[sun]] like [[star]] just 2,400,000 kilometres from the star on average, pushing surface temperatures to an average of 2,575°K. The gravity of 55 Cancri e is around 15 times that of Earth, and the planet is tidally locked. The likelihood of [[diamond]]s on 55 Cancri e is due to the insane pressures on the planet. 55 Cancri E is also known of being up to double the size of Earth. [[Category:Exoplanets]] {{sci-stub}}
