Abstract:

AMONG THE BASIC LAWS OF astronautics are the Keplerian Laws defining not only the movements of the planets around the Sun, but also the movements of artificial satellites around any celestial body, at least on first approximation, i.e. disregarding those influences which might issue from a possibly existent atmosphere, or from the deviations of the celestial body from a sphere with a homogeneous distribution of masses, or from the solar pressure on the orbit.
