Johannes Kepler was born on December 27, , in the Free Imperial City of Weil der Stadt, in what is now Germany. Born prematurely and frail, Kepler faced numerous health challenges throughout his life, including poor vision and chronic illness. Despite these physical limitations, his intellectual abilities were apparent from an early age. His father, Heinrich Kepler, was a mercenary soldier who abandoned the family when Johannes was just five years old, likely to avoid the consequences of debt and war. His mother, Katharina Guldenmann, was a healer and herbalist who faced accusations of witchcraft in later years.

Kepler's early education took place at local schools, where his brilliance was quickly recognized. In , he enrolled at the University of Tübingen on a scholarship, studying philosophy and theology with the aim of becoming a Lutheran minister. There, he encountered the teachings of Michael Maestlin, one of the first astronomers to publicly endorse the Copernican system, which proposed that the Sun, not the Earth, was the center of the universe. This revolutionary idea deeply influenced Kepler and s
Johannes was born in Weil der Stadt (now part of Germany). He had an interest in astronomy from a very young age. When he was 6, his mother took him up to a high place to see the Great Comet of When he was 9, he was called outdoors to see a lunar eclipse. His family were poor, but Johannes got a scholarship to study at the University of Tübingen.
At University, Kepler earned a reputation as a good mathematician and astronomer. When he was 25, he published some of his earlier work in the ‘Mysterium Cosmographicum’. At this time, he was working as a maths teacher.
Johannes was interested in the work of Nicolaus Copernicus, and the Sun-centred model of the Solar System. At the time, the ideas were purely mathematical and had no observational evidence to support them.
Johannes set out to find evidence for the Copernicus’ model. When he was 29, he contacted Tycho Brahe, and asked him to share his most detailed studies of the motions of the planets. Tycho invited Johannes to stay with him at his observatory, but was suspicious and would not share his work. Eventually, Tycho agreed to pay Johannes to work with him to try and solve the problem of why Mars appeared to move backwards
Johannes Kepler was a German astronomer, mathematician and astrologer, who discovered laws of planetary motion. Kepler was a key figure in the Scientific Revolution of the 17th Century &#; confirming the theories of Copernicus and laying the foundation for Issac Newton to discover the laws of gravity. He also worked on optics, inventing an improved version of the refracting telescope. Kepler sought to show that scientific reason was compatible with religion and belief in an intelligent God &#; he described his astronomy as &#;celestial physics.&#;
&#;I feel carried away and possessed by an unutterable rapture over the divine spectacle of heavenly harmony&#; I write a book for the present time, or for posterity. It is all the same to me. It may wait a hundred years for its readers, as God has also waited six thousand years for an onlooker.&#;
