"Which is the 17th century German mathematician and astronomer (at one time assistant to Tycho Brahe) whose works, including "" Epitome of Copernican Astronomy"", provided one of the foundations for Isaac Newton's theory of universal gravitation?"
Johannes Kepler Johannes Kepler Johannes Kepler (; ; December 27, 1571 – November 15, 1630) was a German mathematician, astronomer, and astrologer. Kepler is a key figure in the 17th-century scientific revolution. He is best known for his laws of planetary motion, based on his works "Astronomia nova", "Harmonices Mundi", and "Epitome of Copernican Astronomy". These works also provided one of the foundations for Isaac Newton's theory of universal gravitation. Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe
1677 Tycho Brahe Nova". The official naming citation was published by the Minor Planet Center before November 1977 (). 1677 Tycho Brahe 1677 Tycho Brahe, provisional designation , is a stony Marian asteroid from the central region of the asteroid belt, approximately in diameter. It was discovered on 6 September 1940, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland. The common stony S-type asteroid has a short rotation period of 3.89 hours. It was later named after Tycho Brahe, one of the fathers of astronomy. When applying the hierarchical clustering method to its proper orbital elements, "Tycho Brahe" is a
