Before Kepler outlined his laws of planetary motion in the early 17th century, humankind’s knowledge of the solar system and beyond was in its infancy and largely remained a mystery. At the time ...

German astronomer Johannes Kepler was born in December 1571, and throughout his 59 years of life, he contributed immensely to science. He is most well-known, however, for his three laws of ...

Johannes Kepler was an astronomer best known for his three laws of planetary motion, which describe how the planets move in ellipses around the sun. His name is also well-known thanks to NASA's ...

Johannes Kepler was a 16th century astronomer who established three laws which govern the motion of planets around the sun. These are known as Kepler’s laws of planetary motion.

Of course, most of the readers of 13.7 know this already; they know Kepler discovered the three laws of planetary motion, the first mathematical laws of astronomy: that planets orbit the sun in ...

Four centuries ago, Johannes Kepler established three laws of planetary motion that accurately describe how planets in the solar system orbit the Sun. That might be enough for most; however ...

(These are usually presented as "Kepler's three laws of planetary motion," but taking them together, it’s really just a model.) Planets orbit the sun in elliptical (not circular) paths.

Crowning the achievement is a 6.2-carat Montblanc-cut diamond that rests on the pen’s cap and is surrounded by three diamond-set rings representing, once again, Kepler’s three laws.
