Johannes Kepler Johannes Kepler, a German astronomer, was important to our history for discovering three laws of planetary motion that are now named after him as well as finding key evidence for the highly-debated Sun-centered idea. Kepler’s first law explained that each planet orbits the Sun following an elliptical path with the Sun as aContinue reading “Historical Astronomers in Context” Continue reading →

Johannes Kepler was born on December 27th, 1571 and died on November 15th, 1630. After influential astronomer Tycho Brahe passed away, his unfinished work and data was given to Kepler to continue. With this data, Kepler discovered that Mars’ orbit is an ellipse, publishing Astronomia Nova in 1609 (now known as Kepler’s first two laws). Later in … Continue reading Historical Astronomers in Context → Continue reading →

Johannes Kepler, born December 27, 1571; died November 15, 1630, was hugely important to astronomy as his ideas and, most notably, his three laws, paved the way for important future developments and understanding in the field. His laws helped provide more evidence for the heliocentric idea. He specifically refuted the idea that planets orbit inContinue reading “Historical Astronomers in Context!” Continue reading →

Johannes Kepler was born on December 27, 1571 and died on November 15, 1630. The 30 Year’s War began in 1618 and was a war between the Habsburgs and the French, it resulted in several million deaths and took place in Central Europe. In 1585 the first English colony was established in North America inContinue reading “Historical Astronomers In Context” Continue reading →

Johannes Kepler (1571-1630) was important to astronomy since he came up with three laws to describe planetary motion (Kepler’s laws of planetary motion). The first law states that planets have elliptical orbits with the Sun at one focus of the ellipse while the other focus is just empty space. This is significant because previous astronomersContinue reading “Historical Astronomers in Context” Continue reading →

My chosen astronomer is Johannes Kepler. Kepler was born on December 27, 1571 and died on November 15, 1630. Kepler is mainly credited for establishing his three laws about planetary motion and orbits. Two major historical events that occurred during Kepler’s lifetime were the founding of Jamestown settlement and the start of the Thirty YearsContinue reading “Historical Astronomers in Context” Continue reading →

Johannes Kepler – born on December 27th, 1571 and died on November 15th, 1630. Jamestown – established in 1607. This was the first major English town/colony in the Americas, and it marked the beginning of the settlement of North America. Thirty Years War – began in 1618. This was a major conflict between Protestants andContinue reading “Historical Astronomers in Context” Continue reading →
