'''Kepler-419b''' (also known by its Kepler Object of Interest designation ''KOI-1474.01'') is a [[hot Jupiter]] [[exoplanet]] orbiting the star [[Kepler-419]], the outermost of two such planets discovered by [[NASA]]'s [[Kepler (spacecraft)|Kepler spacecraft]]. It is located about 3,400 [[light-year]]s (1040 [[parsec]]s from Earth in the constellation [[Cygnus (constellation)|Cygnus]].<ref name="Gaia DR2"/><ref name="Dawson"/> The exoplanet was found by using the [[transit method]], in which the dimming effect that a planet causes as it crosses in front of its star is measured.
