Question

If ris the mean distance of a planet from the Sun and T is its orbital time period, then which
of the following quantity remains constant?
If the average distance of the planet from the Sun is rand its orbital period is T, then which
of the following amount remains fixed?​

Answer 1

Answer:

A planet's orbital period is the length of time necessary to complete one revolution around its star. According to Kepler's third law of planetary motion, the square of a planet's orbital period is directly proportional to the cube of its average distance from the sun.
