* Determines, from the data, the period of revolution, the mass of the attractor center, the minimum orbital velocity and the ratio between the angular momentum and the mass of the planet (L / m).[br]* In “planets” determines the semi-major axis, the period, the minimum and maximum orbital speeds and L / m.[br]* In “areas law” occurs the second law of Kepler.
