"Heaven? Where? It's within the hearts, the minds. It's the place where Truth is made manifest! Wherever Truth is made manifest it gives place to that which is heaven for those that seek and love truth!"   ECRL 262-87

Johannes Kepler (1571/1630), based on the Copernican model and on the observations on the motion of the planets of his teacher Tycho Brahe, formulated the THREE Famous LAWS known as THE LAWS OF KEPLER.

They mathematically describe the motion of the planets around the SUN according to elliptical orbits.

His laws laid the foundation for Newton's studies and laws.

In Law (I) and (II) it is highlighted that the motion of the planets is periodic.

1 the first law states that the planets orbit the sun following elliptical orbits where the sun occupies one of the two foci.

The planets of the Solar System have slightly flattened ellipses, that is, close to their circumferences.

2 the second law states that the vector ray connecting the planet to the Sun sweeps equal areas in equal times. This law regulates the orbital speed which varies as its position varies.

The planet travels fastest at perihelion and slowest at aphelion.

The third law, dated 1618, states that the square of the period of revolution

3 the third law, dated 1618, states that the square of the period of revolution of a planet around the sun is proportional to the cube of its distance (semi-axes greater than their orbits).

This ratio is the same for all planets.

It then adjusts the orbital period.
