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)

Responses

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

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

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

The greater the distance, the greater the orbital velocity.

The correct response based on Kepler's observations about planetary motion is:

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

Kepler's Third Law, also known as the law of harmonies, indicates that the square of a planet's orbital period (the time it takes to complete one orbit) is directly proportional to the cube of the semi-major axis of its orbit (which represents the average distance from the sun). Consequently, planets that are farther from the sun move more slowly in their orbits compared to those that are closer.
