2. In 1600, Johannes Kepler met renowned Danish astronomer Tycho Brahe. After Brahe’s sudden death in 1601, Kepler used Brahe’s precise data and discovered that Mars moved in an elliptical orbit.He explained his discoveries (including the suggestion that the sun rotates on its own axis) in...
Johannes Kepler, German astronomer who discovered three major laws of planetary motion. His discoveries turned Nicolaus Copernicus’s Sun-centered system into a dynamic universe, with the Sun actively pushing the planets around in noncircular orbits. Lea
Johannes Kepler was an astronomer and mathematician who discovered that planets and other objects travel in elliptical orbits around the sun, which led to the three laws of planetary motion. His achievements include important work in optics and math. ...

Johannes Kepler suggested the possibility of two moons around the red planet, but only from a numerical standpoint; Earth had one moon and Jupiter, at the time, was known to have four, so the middle planet would likely have two. It wasn't until American astronomer Asaph Hall made a ...
Johannes Kepler also proved gravity with his elliptical orbit law, stating that planets orbit the sun in elliptical orbits with the sun at one focus. It took real insight from Isaac Newton to develop gravity from a normal occurence of objects falling to a measurable and predictable phenomenon. ...
In 1608 Simon Stevin, an engineer, physicist, and mathematician defied many of the then-current misconceptions about ebb and flood. Johannes Kepler, an astrologer, astronomer, and mathematician, suggested that the moon was responsible for tides, in 1609, basing his beliefs on ancient ideas. In...
The existence of the moons had been suggested years before, when Johannes Kepler proposed that since Earth hosted one moon and Jupiter four (as only the Galilean moons were known at the time), Mars might have two moons in orbit around it. However, no signs of such moons existed until Hall...
In honor of the 400th anniversary of Galileo’s first recorded observations with his telescope and the release of Johannes Kepler’s book Astronomia nova, the United Nations declared 2009 to be the International Year of Astronomy. Events throughout the year were held all over the world to promo...
