Steps to Calculate the Period of an Orbit Look up the semi-major axis of the orbit you want to use. Astronomical tables for planets usually list the semi-major axis as the distance from the Sun. The semi-major axes for other bodies are their distances from their centers of rotations. The...
The general representation of functions of two independent variables admitting a derivative in the sense of S. L. Sobolev and the problem of primitives. The gravitational perturbations by Jupiter per orbital revolution are calculated for six selected groups of 1000 hypothetical random comets of low in...
