What Are Kepler's Three Laws Of The Planetary Or Astronomer?

Have you ever wondered how the planets orbit? Do you feel as if it goes in a full circle? Well one astronomer figured out that the planets do not move in a circular motion but in a motion called ellipses. The astronomer’s name is Johannes Kepler. Kepler came up with three laws of planetary motion. He created formulas to explain how long it would take for the planets to make a full revolution around the sun. But before we delve into the laws let’s start with the background of Johannes Kepler.

Johannes Kepler was born on December 27, 1571 in Württemberg, Germany. He lived in a time period where science and religion clashed. One of these clashes involved the science of astronomy. One major astronomer that influenced Kepler was Nicolaus Copernicus. Copernicus gave the idea that the solar system revolved around the sun. The sun was the center. Kepler not only believed this to be true but he later created three laws of planetary motion that proves Copernicus theory.
The first law states that planets orbit the sun in a ellipses motion. A ellipse is a oval in which the sum of the distances from every point on the curve to two other points is a constant. So in the case of planets the sun is a foci point in which it moves. The second law states that no matter the distance from the planet and the sun the area is always equal. This means that if a planet is close to the sun the same distance between the sun and planet is the same as if it was far away. When it is close the area is wider while when the planet is far the area is narrow. The third and last law is the law of Harmonies. This law states that the period of a planet’s orbit squared is the same as the average distance from the sun cubed. This is shown by the formula P^2=A^3.These are the theories that Kepler
