What does Kepler's Third Law state?

• The square of the orbital period of a planet is directly proportional to the cube of its average distance from the sun.

• The square of the orbital period of a planet is directly proportional to its average distance from the moon.

• The orbital period of a planet is directly proportional to its mass.

• The orbital period of a planet is inversely proportional to its average distance from the sun.

What is orbital eccentricity?

• Orbital eccentricity is a measure of how elliptical or circular an orbit is.

• Orbital eccentricity is a measure of the gravitational force between two celestial bodies.

• Orbital eccentricity is a measure of the speed at which a celestial body orbits.

• Orbital eccentricity is a measure of the distance between two celestial bodies.

Which law describes the shape of planetary orbits?

What is the significance of orbital eccentricity in planetary motion?

• Orbital eccentricity only affects the planet's rotation speed.

• Orbital eccentricity determines the shape of the planet's orbit and affects its temperature, climate, and orbital speed.

• Orbital eccentricity has no effect on planetary motion.

• Orbital eccentricity determines the planet's size and mass.

Which law explains why planets move faster when they are closer to the Sun?
