Kepler's Law of Planetary Motion

Description:

Kepler's Laws of Planetary Motion are a set of three fundamental laws proposed by the German astronomer Johannes Kepler in the early 17th century. These laws describe the motion of planets around the sun and revolutionized our understanding of the solar system.

Sample sentences:

1. According to Kepler's First Law of Planetary Motion, each planet moves in an elliptical orbit around the sun.
2. Kepler's Second Law of Planetary Motion states that a planet sweeps out equal areas in equal times as it orbits the sun.
3. The Third Law of Planetary Motion, also known as the harmonic law, establishes a relationship between a planet's orbital period and its average distance from the sun.
