Kepler-84
Kepler-84 is a Sun-like star 4,700 light-years from the Sun. It is a G-type star. The stellar radius measurement has a large uncertainty of 48% as in 2017, complicating the modelling of the star. The Kepler-84 star has two suspected stellar companions. Four red dwarfs are few arcseconds away and at least one is probably gravitationally bound to Kepler-84. Another (which is a background star with a probability 0.5%) is a yellow star of mass 0.855M☉ on projected separations of 0.18±0.05″ or 0.26″ (213.6 AU).
