For which project would knowledge of Kepler's laws prove most useful?

Question

O calculating the mass of Earth
O determining the structure of the solar system's planets
O putting a communications satellite in Earth orbit
O measuring the distance between Earth and the moon

Answer 1

Knowledge of Kepler's laws would prove most useful for determining the structure of the solar system's planets. Kepler's laws describe the motion and orbits of celestial objects, including planets. By applying Kepler's laws, scientists can accurately determine the shape, size, and motion of planets in our solar system.
