We explore the occurrence and detectability of planet-planet occultations (PPOs) in exoplanet systems. These are events during which a planet occults the disk of another planet in the same system, imparting a small photometric signal as its thermal or reflected light is blocked.

Precise and, if possible, accurate characterization of exoplanets cannot be dissociated from the characterization of their host stars.
