Newly discovered exoplanet dethrones former king of Kepler-88 planetary system

A team of astronomers led by the University of Hawaii Institute for Astronomy has discovered a planet three times the mass of Jupiter in the Kepler-88 system. Using W. M. Keck Observatory on Maunakea, Hawaii, the team found that Kepler-88 d is the most massive known planet in this system – not Kepler-88 c as previously thought.
