Kepler-68c is an
Earth-sized planet orbiting the star
Kepler-68 in the
constellation of Cygnus. It was discovered by planetary-transit methods by the
Kepler space telescope
The Kepler space telescope is a disused space telescope launched by NASA in 2009 to discover Earth-sized planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched into an Earth-trailing heliocentric orb ...
in February 2013. It has a mass of 4.8
times that of Earth (0.015
MJ)
and a radius of 0.953 Earth radii. It has an orbital period of 9.605085 days at a distance of about 0.09059
AU from its star. Relatively wide constraints on Kepler-68c's mass are the result lack of detection of the planet through radial-velocity and transit-timing-variation methods.
