It includes a mix of satellites in geostationary (GEO) orbit, sensors on other satellites in highlyellipticalorbit, and ground hardware and software.

Many of the 454 exoplanets discovered to date have highlyellipticalorbits, meaning the planets are not always the same distance from their parent star.
