Kepler-84
Sign in to saveKepler-84 is a Sun-like star 3,339 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 stars, all more than four magnitudes fainter than Kepler-84, are seen within a few arcseconds and at least one is probably gravitationally bound to Kepler-84. Another, which has only a 0.005% chance of being a background star, is a yellow star with mass at a projected separation of 0.18″ or 0.26″ (213.6 AU).
