Kepler-289 (PH3) is a star slightly more massive than the Sun, with an unknown spectral type, 2300 light-years away from Earth. In 2014, three planets were discovered orbiting it.

Planetary system
Kepler-289 hosts four planets, three confirmed (Kepler-289b  , Kepler-289c , Kepler-289d  ) and one unconfirmed candidate (Kepler-289e). The discovery of this system was using the transit method. The inner three planets were found in 2014 with the Kepler space telescope and the Planet Hunters team, while planet e was discovered by follow-up studies. Planet d's eccentricity is not known yet as of 2023.
