The Kepler constant, denoted as k, is a mathematical constant used in Kepler's laws of planetary motion. It is equal to the square root of the gravitational constant G times the mass of the central body, divided by the semi-major axis of the orbit cubed. The Kepler constant helps to describe the relationship between the orbital period and the size of the orbit for a celestial body orbiting around another body under the influence of gravity. **

The Kepler Conjecture is a mathematical problem proposed by German astronomer and mathematician Johannes Kepler in 1611. It deals with the most efficient way to pack spheres in a container, such as a box or a crate. The conjecture states that the most efficient way to pack spheres is in a pyramid-like arrangement, with each sphere touching a certain number of neighboring spheres. The conjecture was finally proven by American mathematician Thomas Hales in 1998, using complex computer-assisted methods. The Kepler Conjecture has important implications in fields such as materials science and engineering, where efficient packing of spheres is crucial. **

Johannes Kepler was a German astronomer and mathematician who is best known for his laws of planetary motion. He worked closely with Tycho Brahe and used Brahe's precise astronomical data to develop his laws, which revolutionized our understanding of the movement of planets. Kepler also made significant contributions to the field of optics and is considered one of the key figures in the scientific revolution of the 17th century. His work laid the foundation for Isaac Newton's theory of universal gravitation. **

Yes, Johannes Kepler is featured on the German 10 Deutsche Mark coin, which was minted from 1969 to 2001. The coin commemorates the 400th anniversary of Kepler's birth and features his portrait on the obverse side. Additionally, there are commemorative coins and medals that have been issued in various countries to honor Kepler's contributions to astronomy and mathematics. These coins are sought after by collectors and can be found in numismatic circles. **
