Kepler-296 is a binary star system in the constellation Draco. The primary star appears to be a late K-type main-sequence star, while the secondary is a red dwarf.
==Planetary system== thumb|The following plot shows the approximate sizes of the planets in this system compared to planets in the Solar System. Five exoplanets have been detected around the system; all are believed to be orbiting the primary star rather than its dimmer companion. Two planets in particular, Kepler-296e and Kepler-296f, are likely located in the habitable zone. For the planetary system to remain stable, no additional giant planets can be located up to orbital radius 10.1 AU.
