How does a planet's distance from the sun affect its period of revolution?
The farther it is from the sun the longer its period of revolution (its "year").
the planets
It's the distance from the Sun that determines the period of revolution. The period squared is proportional to the distance cubed, so if it is at a distance of 4 astronomical units, it takes 8 years to go round.
Yes, the distance of a planet from the sun affects its period of revolution. According to Kepler's third law of planetary motion, planets that are closer to the sun have shorter revolution periods compared to planets that are farther away.
The planets are not all the same distance from the Sun, which determines how far they have to travel, and how fast they are moving. Planets farther from the Sun have much longer orbits and are not moving as quickly. So their period of revolution (year) is longer.
ow does a planet's distance from the sun affect its period of revolution? Note: There are comments associated with this question. See the discussion page to add to the conversation.
The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
The period of revolution of a planet (time taken to complete one orbit around the sun) is directly proportional to its average distance from the sun. This relationship is described by Kepler's third law of planetary motion. Planets that are farther from the sun take longer to complete an orbit compared to planets that are closer to the sun.
A planets period or revolution, the time taken to orbit its star, is dependant on its mass, the stars mass and the distance between the two. See Kepler's laws of planetary motion for further information.
