All bodies in the solar system experience the attraction of the sun and the pressure of sunlight. How do these factors depend on the size of the bodies?

For large bodies, the effect of sunlight pressure is negligible. So, for the Earth, the force of gravity exceeds the force of light pressure by 10 ^ 13 times. But for dust grains less than 10 ^ -6 m in size, the pressure of sunlight is predominant.
