These are some laws that were created to explain mathematically, how is the movement of the planets around the king star (the sun). The person who enunciated these laws was the German-born astronomer Johannes Kepler, who dedicated himself to describing the displacement of the planets, based on three mathematical expressions, in addition to this, he discovered that the orbits of the planets were not circular but were elliptical.
The laws formulated by Kepler, not only, are applied to the planets, but also cover all the celestial bodies that are orbiting, influenced by gravity.
One of the conclusions that Kepler reached is that celestial bodies tend to move around the sun in an elliptical way, the sun being one of the points.
Other arguments raised by the astronomer is that the line that holds the planet together with the sun is determined by similar areas. Kepler created this hypothesis by incorporating into his research a system made up of these six planets: Jupiter, Mars, Earth, Venus, Saturn and Mercury.
The laws formulated by Kepler are as follows:
- The first law was enunciated in the year 1609 and stated that all the planets revolve around the sun, delineating an elliptical path.
- The second law was also formulated in the year 1609 and expresses the variation in the speed of a planet at different points in its orbit.
- The third law states that regardless of the planet, the square of its orbital phase is openly proportional to the cube of the extension of the upper semi-axis of the elliptical orbit.
