    Gravity along a shifted sun-earth line?

    Hi Nomadreid, I should admit here that I don't know the answer to your specific question, but just a thought. We are talking about a distance which is 8 x 60 X c meters = 8 x 60 x 3 X 10^8 meters. How much difference will it make in terms of vector angle towards the direction of sun. Also...
