Kepler-68d is a gas giant with the minimum mass about the same as Jupiter. It is at least a jovian-mass planet orbiting 1.4 astronomical units from its parent star, Kepler-68, well within habitable zone of the star.[2] It was detected by radial velocity.[3]

Discovery
Discovery date	February 12, 2013
Detection method	Radial velocity
Orbital characteristics
Periastron	1.148 AU
Apoastron	1.652 AU
Semi-major axis	1.4±0.03 AU[1]
Eccentricity	0.18 ± 0.05
Orbital period (sidereal)	580±50 d

After planets Kepler-68b and c were detected by observing planetary transits in front of its star, doppler spectroscopy measurements were used to make follow-up observations of the star. Kepler-68d was discovered using that method.
