Provided is a satellite comprising a filtering unit for preventing damage to a photosensor by controlling the transmissivity of light inputted into the photosensor. The satellite can comprise: a photosensor for acquiring data associated with the satellite by using the light transmitted to the satellite; a communication unit for receiving, from a control center of the satellite, a first command signal for controlling the intensity of the light; and a filtering unit for controlling the transmissivity of the light according to the first command signal so as to prevent damage to the photosensor.
