Kepler-462, aka KOI-89, is an oblate A-type main sequence star located about 1979.10 light-years from the solar system. Two planets are currently known to orbit this star, both around the size of Neptune, one on an intermediate period orbit and the other on a long period orbit. the outer planet experiences strong TTVs while the inner one shows little. This could be indicative of a very high mass inner planet with a mass greater than or equal to 20 Me, or another planet on a longer orbit. While both conclusions can explain Kepler-462 c's strong TTVs, current understandings slightly prefer a two-planet model, with highly unconstrained masses for both planets.
