What is the planetary movement?
As the planets move, it is one of the earliest questions that the old scientists have faced to try to determine the rules of the universe. Early theories assumed that the Earth was the center of the universe and circulated all the heavenly objects around it. In Galile's findings, the sun, not the Earth, was the center of our solar system, and the planets were moving around it different speeds and angles. Today's theory of planetary movement is based on the work of German astronomer of the 16th century Johannes Kepler. Although only six planets were known at that time, its theory was confirmed more than a century later by Newton and held well for more than 400 years. Although his theories are somewhat confusing to the non -regter, they have significantly changed the playground for the world of planetary science.
The first law that Kepler determined was that planetary movement was elliptical rather than cyclical. Rather than moving in a circular pattern around the sun, each planet moves in an oval orbit. This law was in complete disapproval ofThe theory of planetary movement that existed since the time of Aristotle, but the stunning scientific evidence eventually showed that Kepler's new theory was true.
Kepler's second law deals with the speed planets move while they follow their orbit. Planets change speed relative to their position into the sun; When they are closer, they accelerate and slow down when they are on. Kepler's second law states that for the same time the planet moves the same distance. In principle, the distance that would travel in one month slower, but have less distance to cover. Under this Planetary Motion Act, the speed balances the distance, so that the planet almost always covers the same distance in a given period of time.
The third law of the planetary movement that Kepler devoted to is more mathematical and more complicated. While the first two laws deal with how the planet moves inE Comparison with the Sun, the third law compares the movement of the planet with other planets. In principle, it was stated if the square amount of time the planet insists to complete the orbit and divide it with the average distance of the planet to the sun, you will come with almost the same ratio for each planet. This means that the orbiting time of the planet is directly proportional to how large the orbit is, so the ratio is almost exactly the same regardless of what the planet is described.
planetary movement helps to describe the rules of the solar system, but its usefulness does not end there. In addition to the explanations, the planets move, it also helps modern scientists to identify the orbital patterns of satellites and other objects produced into space. Kepler's laws also helped explain the orbiting formula of new planets that have been discovered by advanced technology, even if we cannot visually observe them.
