- A uniform distribution of dust in the solar system adds to the gravitational attraction of the Sun on a planet an additional forceF = −m C rwhere m is the mass of the planet, C is a constant proportional to the gravitational constant and the density of the dust, and r is the radius vector from the Sun to the planet (both considered as points).
