A satellite watching system exchanges watching information with a lunar and planetary exploration satellite, when a watching satellite passes through a vicinity of the lunar and planetary exploration satellite, and the lunar and planetary exploration satellite exchanges the watching information with a watching center via the cislunar data relay satellite. Each satellite in an infrastructure satellite cluster and a watching satellite cluster includes a bidirectional communication standard terminal with a transmission/reception switching device. The watching center operates the transmission/reception switching device, based on a data amount α of commands that are transmitted to the watching satellite and a data amount β of watching data and telemetry data that are received from the watching satellite, so that a ratio between reception time and transmission time of the watching satellite becomes α versus β, and carries out exchange of information with the watching satellite cluster via the lunar and planetary exploration satellite.
