Kepler-453b is a
transiting circumbinary
A circumbinary planet is a planet that orbits two stars instead of one. The two stars orbit each other in a binary system, while the planet typically orbits farther from the center of the system than either of the two stars. In contrast, circums ...

. It orbits the binary system in the
habitable zone every 240.5 days.
