Historical Astronomers in Context: Johannes Kepler

Johannes Kepler succeeded his mentor, Tycho Brahe, in his attempt to explain the motion of planets. Kepler used Brahe’s data on the paths of planets – with particular discern for Mars – to postulate the three laws of planetary motion as they are known today. They are (1) the orbit of each planet about the … Continue reading Historical Astronomers in Context: Johannes Kepler Continue reading Continue reading

Historical Astronomers in Context – Johannes Kepler

Johannes Kepler. (Dec.27.1571 – Nov.15.1630) He was important to astronomy for his revolutionary discovery of laws of planetary motion, and his books Astronomia nova, Harmonices Mundi, and Epitome Astronomiae Copernicanae. His laws of planetary motion describe how planets orbit around the Sun and the relationship between their period and their orbit length. His works contribute to Newton’s theory … Continue reading Historical Astronomers in Context – Johannes Kepler Continue reading Continue reading

Johannes Kepler was born in the German town of Weil der Stadt on December 27, 1571. Kepler was one of the most significant astronomers in history. He developed the current heliocentric model of planetary motion using Tycho Brahe’s naked eye observations. Contrasting his previous beliefs, Kepler discovered that planets orbit the sun in ellipses, not … Continue reading Historical Astronomers in Context Continue reading Continue reading

Some Context…

I thought to start out the semester, I would look back and provide a little context for myself and everyone else as to how we as humans used to do astronomy. I learned some of the basics of the history of astronomy in a class called the Scientific Revolution. We discussed some of the big […] Continue reading Continue reading

Johannes Kepler: A Sign of the Times

Today I want to talk about Johannes Kepler (Born on December 27, 1571 at 1 PM; Died November 15, 1630). Kepler was the guy who came up with the three laws of planetary motion and basically, is the reason why we know how planets orbit things today (NASA). But did you know what was going on … Continue reading Johannes Kepler: A Sign of the Times Continue reading Continue reading

Historical Astronomers in Context

Johannes Kepler’s (December 27, 1571 – November 15, 1630) primary contribution to the astronomy field was his laws of planetary motion. Not only are these concepts important to modern day astrophysics (such as when sending satellites to study distant planets), but also lay the foundation for Newton’s work on universal gravitation. One major astronomical event that happened […] Continue reading Continue reading
