Kepler-1704b is a super-Jupiter on a highly eccentric orbit around the star Kepler-1704. It has a mass of 4.51 . 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.[2]
Characteristics
Kepler-1704b is much more massive than Jupiter, at 4.51 MJ. The high planetary mass makes Kepler-1704b a super-Jupiter. Kepler-1704b goes on a highly eccentric 2.7 year-long (988.88 days) orbit around its star as well as transiting. The extreme eccentricity yields a temperature difference of up to 700 K.
Star
The star, Kepler-1704, is a G2, 5745-kelvin star 825pc from Earth and the sun. It has a mass of, a radius of, and a luminosity of . The high radius for the star's mass hints that Kepler-1704 is not a main-sequence star.[3]
