A solar sail allows a spacecraft to use radiation pressure for propulsion, similar to the way wind propels a sailboat. The sails of such spacecraft are made out of enormous reflecting panels. The area of the panels is maximized to catch the largest number of incident photons, thus maximizing the momentum transfer from the incident radiation. If such a spacecraft were to be simply pushed away from a star by the incident photons, the force of the radiation pressure would have to be be greater than the gravitational attraction from the star emitting the photons. The critical parameter is the area density (mass per unit area) of the sail.
