单词	Kepler's laws
释义	Kepler's laws Three laws of planetary motion formulated by Johannes Kepler in about 1610 on the basis of observations made by Tycho Brahe (1546–1601). They state that: (1) the orbits of the planets are elliptical with the sun at one focus of the ellipse; (2) each planet revolves around the sun so that an imaginary line (the radius vector ) connecting the planet to the sun sweeps out equal areas in equal times; (3) the ratio of the square of each planet's sidereal period to the cube of its distance from the sun is a constant for all the planets.
