Radiation pressure is defined as the force per unit area exerted by electromagnetic radiation, and is given by

where p is the momentum, c is the speed of light, and is then energy flux.

For relativistic particles, the radiation pressure P is related to the radiation density u by


a is the radiation constant and T is the temperature.

In the solar system, radiation pressure pushes particles of size outward.
