The Poynting–Robertson effect, also known as Poynting–Robertson drag, named after John Henry Poynting and Howard P. Robertson, is a process by which solar radiation causes a dust grain orbiting a star to lose angular momentum relative to its orbit around the star.

The Poynting-Robertson Effect refers to the mechanism by which small particles in the solar system, such as interplanetary dust particles, are brought to Earth due to the gradual loss of momentum caused by solar radiation pressure.

May 27, 2024 · The Poynting-Robertson effect is essentially a form of drag that occurs when sunlight interacts with dust particles orbiting the Sun. It involves two primary components of physics: the absorption and re-emission of light.

Poynting–Robertson effect are the best known of all the radiation forces. Poynting–Robertson is a V/c effect (where V is the speed and c is the speed of light); it causes orbit decay for dust or ice par-ticles orbiting a luminous body (e.g., Poynting, 1903; Robertson, 1937; Burns et al., 1979). Being a surface-to-mass effect, the smal-

May 28, 2024 · The Poynting-Robertson effect, named after John Henry Poynting and Howard Percy Robertson, is a fascinating relativistic phenomenon that illustrates how light can influence the motion of particles in space.

Nov 16, 2021 · This will give rise to a non-radial ’drag’ force, called Poynting-Robertson drag, which will result in the slow spiral of the grain in towards the star, where it will eventually be destroyed by dust sublimation or sputtering, or collide to form much smaller grains which are then launched out of the solar system on hyperbolic orbits (since ...

The Poynting-Robertson effect is the radiation pressure produced by the Sun’s rays striking the small particles orbiting it, causing them to slow down and spiral towards the gigantic ball of fire. More specifically, this refers to the Sun’s radiation and gravity working together to form an interstellar giant vacuum that sucks in tons and ...

Apr 23, 2024 · The Poynting-Robertson Effect, named after John Henry Poynting and Howard P. Robertson, is a phenomenon in astrodynamics that describes the effect of radiation pressure on small particles in space. When a small particle, such as a dust grain or asteroid, is exposed to sunlight, it absorbs and re-emits photons, causing a transfer of momentum.

Apr 1, 2014 · The force associated with the action of electromagnetic radiation on a moving spherical body (dust particle) is called the Poynting–Robertson (P–R) effect. It is used in astrophysical modelling of orbital evolution of dust grains for many decades.

Nov 4, 2023 · In the Poynting Robertson effect, it says in general, the Poynting Robertson effect is caused by the fact that objects like dust re-emit the light they absorb. Is that correct? Is this effect weak? Where does it apply and where it does not?
