Based on Kepler's third law of motion, what is the relationship between a planet's orbital velocity and its distance from the sun?

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

B)Distance has no effect on orbital velocity.

C)As distance is cut in half orbital velocity decreases.

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

Based on Kepler's third law of motion, the relationship between a planet's orbital velocity and its distance from the sun is

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

Step-by-step explanation:

  • A planet's orbital speed changes, depending on how far it is from the Sun. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
  • A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
  • Kepler's first law - sometimes referred to as the law of ellipses - explains that planets are orbiting the sun in a path described as an ellipse.
  • The resulting shape will be an ellipse. An ellipse is a special curve in which the sum of the distances from every point on the curve to two other points is a constant.
  • Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times. Thus, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.
  • Kepler's Third Law. “The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit” That's Kepler's third law. In other words, if you square the 'year' of each planet, and divide it by the cube of its distance to the Sun, you get the same number, for all planets
