Different points in the earth are at slightly different distances from the sun and hence, experience different forces due to gravitation. For a rigid body, we know that if various forces act at various points in it, the resultant motion is as if a net force acts on the (centre of mass) causing translation and a net torque at the causing rotation around an axis through the .
