Analysis of the orbital motion of the Earth, the Moon and other planets
and their satellites led to the discovery that all bodies in the Solar
System are moving with the first cosmic velocity of their proto parents.
The mean orbital velocity of each planet is equal to the first cosmic
velocity of the Protosun, the radius of which is equal to the semi-major
axis of the planet's orbit. The same applies for the planets'
satellites. All the small planets, comets, other bodies and the Sun
itself follow this law, a finding that has also been proven by
astronomical observations. The theoretical solutions based on the Jacobi
dynamics explain the process of the system creation and decay, as well
as the nature of Kepler's laws.
