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 →

Johannes Kepler December 27th, 1571 – November 15th, 1630 Image Source: High Altitude Observatory Kepler was a German astronomer and mathematician whose greatest contribution to the field of astronomy were his three planetary laws of motion. Using mathematical calculations, he discovered orbits are ellipses and that within such orbits, equal areas are swept out within […] Continue reading →

Johannes Kepler was born on Dec. 27, 1571 and died on May 21, 1630. He was important to astronomy because he made 3 key astronomical discoveries. First, and arguably most importantly, he discovered that planetary orbits are ellipses and not perfect circles as is it was popularly believed to be at the time. This was … Continue reading Historical Astronomers in Context → Continue reading →

Johannes Kepler (December 27, 1571- November 15, 1630), summarized his discoveries with three physical principles. First, the planets move in elliptical orbits, but not perfect circles, with the Sun at one focus. Second, he argued that the time necessary to traverse any arc of a planetary orbit is proportional to the area of the sector between … Continue reading Historical Astronomers in Context → Continue reading →
