Which of the following statements or expressions is most nearly associated with kepler's third law of planetary motion? (2 points) p2 = a3 planetary orbits revolve around two foci. a planet moves fastest when it is farthest from the sun. a planet moves slowest when it is farthest from the sun.

Kepler's third law of planetary motion states that:
"The ratio between the cube of the orbital radius of the planet and the square of the orbital period is constant". In formulas:

where r is the orbital radius and T the orbital period.

Since this ratio is constant for every planet, we see that when the orbital radius r is larger (i.e. when the planet is farther from the Sun), the orbital period T is larger: this means the planet takes more time to complete one revolution around the Sun, so it moves slower.

Therefore, the correct option is:
A planet moves slowest when it is farthest from the sun.

Which principle states: "geologic processes taking place on earth today operated similarly in the past and can be used to explain past geologic events"? a. lateral continuity
