Johannes Kepler's Accomplishments

Johannes Kepler was an infamous astronomer who had many ideas. He was very important during the Elizabethan era. At first nobody really listened to what he said but after years and years of work, he started to influence people. He created three major laws that influenced Isaac Newton. Even though Johannes Kepler wasn’t very well known, he greatly contributed to the knowledge of science during the Elizabethan era. Johannes Kepler published four books that showed his ideas and works. The first book that he published was called Astronomia Nova (Dunbar). This book, published in 1597, showed that he found that the sun rotates on an axis and it contained his first two laws. (Dunbar). This book was a huge influence on many people. In 1609, Kepler published a book called The Cosmographic Mystery (Helden). In this, he supported …show more content…
One thing Kepler found out is that the sun is a focus point for all of the planets’ orbits (Dunbar). He also found out that the planets move in ellipses and not in circles (Dunbar). He was very smart because he was able to find these things out and he was actually correct on both of these ideas. He also found out that planets didn’t move at a constant speed. Kepler found that planets move faster as they get closer to the sun and slower as they move away (Dunbar). In a way, the planets are getting sling shotted around the sun. Johannes Kepler also found that some stars move relative to each other, but most of them don’t (Tycho…). This basically means that some stars orbit each other, but most of them don’t. Kepler also found that the moon is the cause of tides and waves (Dunbar). These ideas had a huge influence on Isaac Newton. According to Brian Dunbar, Kepler was the first person to describe real, virtual, upright, and inverted images. He also said that Kepler was the first person to describe magnification. These were all great ideas that took a great mind like Kepler’s to come up
