Yarkovsky effect

Not to be confused with Yarkovsky–O'Keefe–Radzievskii–Paddack effect.
Yarkovsky effect:
  1. Radiation from asteroid's surface
  2. Prograde rotating asteroid
    • 2.1. Location with "Afternoon"
  3. Asteroid's orbit
  4. Radiation from Sun

The Yarkovsky effect is a force acting on a rotating body in space caused by the anisotropic emission of thermal photons, which carry momentum. It is usually considered in relation to meteoroids or small asteroids (about 10 cm to 10 km in diameter), as its influence is most significant for these bodies.
