Johannes Kepler was born on December 27, 1571 and died on November 15, 1630. He was a German astronomer that discovered three important laws of planetary motion. The first law of motion was the planets move in elliptical orbits and with the sun at one focus. The second law of motion was the time necessary to traverse any arc of a planetary orbit is proportional to the area of the sector between the central body and the arc. The third law was there is an exact relationship between the squares of the planet's' periodic times and the cubes or the radii of their orbits. Kepler did not refers to these discoveries as "laws" but as celestial harmonies the reflected God's design for the universe. Scientist believed that the planets in the solar system …show more content…
The sun did not sit exactly in the center of their orbit, but instead it lay of to the side, at one of the two points known as the focus. Some planets, such as earth, had an orbit that was extremely close to a circle. The orbit of Mars was one of the most eccentric, or widely stretched. The fact that planets travel on elliptical path known as Kepler's First Law. Kepler struggled with changes in the velocities of the planets. He figured out that planets move slower when it was farther away from the sun than it did when nearby. He then realized that an invisible line connecting the sun to a planet covered an equal amount of area over the same amount of time. This concept became his second law, along with his first law which he later published in 1609. His third law was published a decade later, and recognized that the relationship between the period of the two planets, the time they take to orbit the sun, is connected to their distance from the sun. The square of the ratio of the period of two planets is equal to the cube of the ratio of their radius. Kepler's first two laws focus on the specifics of a single planet's movement, his third law is focused on a comparison between the orbit of two

Johannes Kepler Johannes Kepler was born on December 27, 1571 in Weil der Stadt, Württemberg in the Holy Roman Empire of German Nationality. Although being very intelligent from an early age, Kepler grew up in a fairly poor family. His father, Heinrich, was an uncommitted father. Heinrich consistently left his family made up of Katherine Gouldenmann, his wife, and their seven children. He left them for good in 1588, when Kepler was at the age of 17. Three of Kepler’s siblings died as children…

Johannes Kepler Research Paper

Johannes Kepler came up with three laws about planetary motion. The first law states that all planets move around the Sun in an elliptical orbit. The second law is that a radius vector that connects any of the planets to the Sun sweeps out equal areas of equal amounts of time. Meaning if a planet is close to the Sun, the invisible line that connects it is shorter, it moves quicker, and sweeps over the same area as if the planet would be far away. Kepler's third law is that a planet's orbital squared…

Galileo And Kepler's Changing Ideas During The Scientific Revolution

Kepler changed the traditional interpretations of nature by combining and searching though observation data collected from his mentor Tyco Brahe and using mathematics to develop his three laws on planetary motion. These laws are still used today. The first law explained how each planet moves in an elliptical orbit with sun at its focus. Previously it was thought that the Earth was the center. The second law explained the line connection between the sun…

He thought that the planets travelled on spheres of their own. To account for the more subtle motions, Ptolemy believed that each planet also moved on a smaller sphere - an epicycle. Ptolemy's view of the universe was thought to be valid and current for 1,500 years, But he was proven wrong by Galileo Galilei in 1609 when he came along and looked at…
