Geodesic Effect Near an Elliptical Orbit

الملخص EN

Using a differential geometric treatment, we analytically derived the expression for De Sitter (geodesic) precession in the elliptical motion of the Earth through the gravitational field of the Sun with Schwarzschild's metric.

The expression obtained in this paper in a simple way, using a classical approach, agrees with that given in B.
