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.
