Solar radiation pressure is the force exerted by electromagnetic radiation originating from the Sun upon objects in its path, resulting from the transfer of photon momentum. As an academic concept and research area within physics and engineering, it investigates the magnitude and effects of this non-gravitational perturbation on the motion and orientation of celestial bodies, spacecraft, and orbital debris. Key characteristics include its dependence on the object's surface properties, geometry, mass, and heliocentric distance, making its accurate modeling critical for precision astrodynamics, satellite navigation, and mission design.
