What are Kepler's laws?
Kepler's laws are three equations that control the movement of astronomical bodies. Kepler's laws were first discovered by the 17th century by Johannes Kepler in the analysis of the data collected by Tycho Brahe. Kepler's laws are an extension of the earlier Helocentric theory of Copernicus and eventually paved the way for the complete theory of Isaac Newton about how the bodies interact. Newton's gravity and movement equations can be used to derive Kepler's laws if you assume that there are only two bodies, one of which is solid, and one of them orbit at less than escape speeds. Although Kepler's laws were originally developed to explain planetary movements, they relate to any body that is in orbit around a much massive body.
The first of Kepler's law states that the planet or any other object in orbit around the Sun is watching an elliptical path with the sun on one focus. The shape of these ellipses depends on the solar mass, the position of the planet and the speed of the planet. Assad six numbers, NazEmped Keplerian Elements can be used to determine the exact path that the planet follows.
The second of Kepler's law says that the planet in orbit monitors the same areas at the same time. If you draw a line from the planet to the sun and add up the area that the line sweeps over a given time interval is always constant. This law is the result of maintaining angular momentum; If the planet moves faster, it must also be closer to the sun. Increasing the area covered with greater angular movement and a decrease in the area covered from a shorter distance must be canceled exactly.
The third law states that the square period of the orbit must be directly proportional to the cube of the semi-major axis of the orbit. The Polo-Major axis is half the total distance between Perihelion or the closest access to the Sun, and Aphelion or the farthest distance from the Sun. Planet very far from the sun like Neptune has much sentencesthe orbit of the orbit; It also moves slower and takes more time to cover the same distance than the planet as Mercury. Isaac Newton later developed the exact relationship between the orbital period, the semi-major axis, matter and gravitational constant.
