Exoplanet 3 times the mass of Jupiter discovered, claim astronomers

Astronomers led by University of Hawaii Institute for Astronomy claim to have discovered an exoplanet three times of Jupiter's mass orbiting the star Kepler-88. The planet takes four Earth years to go around its star. Previously, two other exoplanets orbiting Kepler-88, Kepler-88 b and Kepler-88 c were discovered. Kepler-88 c, Jupiter-mass planet, takes 22 days to go around the star.
