Question

Kepler's law of planetary motion formula

Answer 1

The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus. ... The Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times. 3. The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.

Answer 2

Only the third law has a formula.

The square of the time period of a planet is directly proportional to the cubeof it's orbit's average radius.

T^2 is directly proportional to R^3.
