Perhaps the most famous exoplanet in the constellation is 55 Cancri e, a super-Earth that was (for a time) identified as a " diamond world ." The original observations in 2010 suggested that the host star had more carbon than oxygen in its interior. A subsequent 2012 study then modeled 55 Cancri e’s mass and radius, based on the composition of its planet star, and suggested this planet had a graphite surface overlying a massive layer of diamond underneath.

The consolation of Cancer has several exoplanets found in it, with the most notable exoplanet being 55 Cancri e. 55 Cancri e was once called a “diamond world”, though it is no longer referred to as such. Observations of the exoplanet originally taken in 2010 suggested that the star the planet revolves around possessed more carbon than oxygen within the interior of the star. During 2012 another study examined the radius and mass of the exoplanet and based on the star’s composition it was hypothesized that the planet possessed a massive graphite surface fitted over a substantial layer of diamond.
