Question

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

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

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.

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 reflects Kepler's Third Law of Planetary Motion, which states that the square of the orbital period of a planet is proportional to the cube of its average distance from the sun. As a result, planets that are farther from the sun move more slowly in their orbits compared to those that are closer.
