Johannes Kepler was born on December 27, 1571, in the town of Weil der Stadt, which is now known as Germany. When Johannes was five years old, his father, Heinrich Kepler, was killed in Holland fighting as a mercenary. His mother, Katharina Guldenmann, helped run an inn owned by her father. His hands were crippled and his eyesight permanently impaired by smallpox. Despite these difficulties, he had the ability to solve any math problem that was brought to him by guests at his grandfather inn. His mother made a point of taking him out at night to show him interesting things in the sky, for example a comet and a lunar eclipse. Kepler was schooled in Latin, and then he attended the Protestant Seminary of Maulbronn, because he wanted to become …show more content…

There are three laws to Kepler’s laws of planetary motion. The first law states “The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus. (The Law of Ellipses)”. Next, the second law states “An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time. (The Law of Equal Areas)”. Finally, the third law states “The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. (The Law of Harmonies)”. Kepler was one of the first to incorporate the field of physics and the field of astronomy. This caused some controversy, however his ideas became more widely read and accepted after his …show more content…

A planet moves fastest when it is closest to the sun and slowest when it is furthest from the sun. Kepler's third law compares the orbital period and radius of orbit of a planet to those of other planets. Unlike Kepler's first and second laws that describe the motion characteristics of a single planet, the third law makes a comparison between the motion characteristics of different planets.The comparison being made is that the ratio of the squares of the periods to the cubes of their average distances from the sun is the same for every one of the planets. Kepler's third law provides an accurate description of the period and distance for a planet's orbits about the sun. However, Kepler made many other contributions to science as well. He discovered a new star (a supernova); he analysed how the human eye works; he made improvements to the telescope, and made other contributions in the field of optics (the study of light).. He published accurate data on the positions of stars and planets which were of valuable to navigators.He made various contributions to mathematics, including faster methods of calculation, and investigated the volume of many solid bodies. Kepler also spent time investigating the dating of historical events in the Bible, including the birth of Jesus. In addition, he wrote a story called The Dream which
