Poynting-Robertson Effect
The Poynting-Robertson Effect is a phenomenon in which the solar radiation exerts a force on small particles in space, causing them to lose energy and spiral towards the sun. This effect is caused by the absorption and re-emission of photons by the particle, which results in a net transfer of momentum from the photon to the particle. The effect is most pronounced for small particles, such as dust grains, and can have a significant impact on the dynamics of dust in the solar system. The Poynting-Robertson Effect is an important consideration for spacecraft design and mission planning, as it can affect the trajectory and lifetime of spacecraft in orbit around the sun.
