55 Cancri e

(55 Cnc e)
(superearth orbiting a Sun-like star)

55 Cancri e (55 Cnc e) is a Super-Earth of about 8.6 Earth masses, orbiting a G-Type Star, but close to the star with an orbital period of about 18 hours. Its density was estimated from estimates of the host star's mass and radius along with data from observed Transits and the star's Radial Velocity, yielding a radius of roughly 2 Earth radii and a density slightly (5%-10%) more than Earth's. Given its proximity to he star, the Temperature of the star-facing side has been calculated to be higher than 2000k.
