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

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

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

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

The greater the distance, the slower the orbital velocity.

Answer 1

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

The greater the distance, the slower the orbital velocity.

This relationship is part of Kepler's Third Law, which states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit. As a result, planets that are further from the sun move more slowly in their orbits compared to those that are closer.
