Based on Kepler's observations about planetary motion, what is the relationship between a planet's orbital velocity and its distance from the sun?(1 point)

Question

Responses

As distance is cut in half, orbital velocity decreases.
As distance is cut in half, orbital velocity decreases.

The greater the distance, the slower the orbital velocity.
The greater the distance, the slower the orbital velocity.

Distance has no effect on orbital velocity.
Distance has no effect on orbital velocity.

The greater the distance, the greater the orbital velocity.

Answer 1

The correct response is:

The greater the distance, the slower the orbital velocity.

Kepler's laws of planetary motion indicate that planets closer to the Sun move faster in their orbits than those that are farther away. Specifically, Kepler's Third Law states that the square of a planet's orbital period is directly proportional to the cube of the semi-major axis of its orbit, which implies that the farther a planet is from the Sun, the slower its orbital velocity.
