What is the ratio of the spin angular momentum of the earth and its orbital angular momentum about the sun. The mean radius of the earth is R=6400km. The radius of the earth's orbit is r=1.5*10^8km. You may assume the mass of the earth is uniformly distributed throughout its volume.

L=I omega = 2/5 MR^2.
Thanks for your help.
