What must you know to solve kepler's third law, the law of periods? a. period of the minor axis b. period of the orbit c. period of the revolution around the sun d. period of the major axis

Explanation:

According to the Third Kepler’s Law of Planetary motion “The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”.

Talking in general, this law states a relation between the orbital period of a body (moon, planet, satellite) orbiting a greater body in space with the size of its orbit.

This Law is originally expressed as follows:

Where;

is the Gravitational Constant

is the mass of the massive (greater) body

 is the semimajor axis of the orbit of the smaller body
