Kepler-453b is a transitingcircumbinaryexoplanet in the binary-star system Kepler-453. It orbits the binary system in the habitable zone every 240.5 days.[1][2] The orbit of the planet is inclined relative to the binary orbit therefore precession of the orbit leads to it spending most of its time in a non-transiting configuration. By the time the TESS and PLATO spacecraft are available for follow up observations it will no longer be transiting.[3]
