Which of these describes Kepler’s third law of orbital motion?(1 point)

Question

Responses

A) T^2∝a

B) T∝a^2

C) T^3 ∝a^2

D) T^2 ∝ a^3

Answer 1

Kepler's third law of orbital motion states that the square of the orbital period (T) of a planet is directly proportional to the cube of the semi-major axis (a) of its orbit. Therefore, the correct response is:

D) T^2 ∝ a^3
