Kepler-88 is a G-type star 1,230 light-years (380 parsecs) away in the constellation of Lyra, with three confirmed exoplanets.[5] SIMBAD lists a subgiant spectral type of G8IV,[2] while other sources give it a main sequence spectral type of G6V.[3] The latter is more consistent with its properties (it is less luminous than the Sun).
