Kepler-1704b is a super-Jupiter on a highly eccentric orbit around the star Kepler-1704. It has a mass of 4.51 MJ. The planet's distance from its star varies from 0.16 to 3.9 AU. It is a failed hot Jupiter, having been scattered from its birth orbit to orbit with a periastron just above the tidal circularization distance.[1]
