Motion of the Earth
We now consider the orbital motion, or revolution, of the Earth around the Sun, in the sense of Copernicus, and also the rotation of the Earth around its axis as well as the motion of the axis itself. Here we adopt the observer’s standpoint. We shall develop Newton’s theory of the motions of the Earth and the planets in accordance with his theories of mechanics and gravitation in Chapter 6.
