⚫ | '''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]].

Kepler-419c orbits its host star with 270% of the Sun's luminosity (2.7 {{solar luminosity}}) about every 67 days at a distance of 0.37 [[astronomical unit|AU]] (close to the orbital distance of Mercury from the Sun, which is 0.38 AU). It has a highly eccentric orbit, with an eccentricity of 0.833. |

In 2009, [[NASA]]'s [[Kepler (spacecraft)|Kepler]] spacecraft was completing observing stars on its [[photometer]], the instrument it uses to detect [[transit method|transit]] events, in which a planet crosses in front of and dims its host star for a brief and roughly regular period of time. In this last test, Kepler observed {{val|50,000}} stars in the [[Kepler Input Catalog]], including Kepler-419, the preliminary light curves were sent to the Kepler science team for analysis, who chose obvious planetary companions from the bunch for follow-up at observatories. Observations for the potential exoplanet candidates took place between 13 May 2009 and 17 March 2012. After observing the respective transits, the first planet, Kepler-419b, was announced. |
