Detailed explanation1: (The Law of Equal Areas) The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun.
Detailed explanation2: Kepler’s law of harmonies proposed that the ratio of the square of the periods of any two planets is equal to the ratio of the cube of their average distances from the sun.
Detailed explanation3: A planet’s orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun’s gravitational pull, and the slower it moves in its orbit.
Detailed explanation4: Kepler’s 3rd Law is sometimes called The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.
Detailed explanation5: The ratio of orbital periods is 31.6:1. Note that the distances and orbital periods for planets X and Y are similar to the distances and orbital periods for Earth and Saturn in their orbits around the Sun. Drive Student Mastery. Unlock Skills Practice and Learning Content.
