A planet's rotation on its axis determines the length of its day.


What is the relationship between a planets movement and a planets rotation and revolution?

Each year, the planet moves one full rotation around the sun, a movement. Each day, the planet revolves once, that's why in the day there is light because you are facing the sun, but when the earth revolves some more it is facing away from the sun eliminating the sun's light.


Why do planets nearer to the sun have shorter year length?

Planets closer to the Sun have shorter year lengths because they orbit the Sun at higher speeds due to stronger gravitational forces. The closer a planet is to the Sun, the less distance it has to travel in its orbit, allowing it to complete a revolution more quickly. This results in shorter orbital periods, which defines the length of a year for those planets. For example, Mercury, the closest planet, takes only about 88 Earth days to complete one orbit around the Sun.


What planetary motion determines length of year?

The length of a year is determined by the Earth's orbital motion around the Sun. Specifically, it takes approximately 365.25 days for the Earth to complete one full revolution around the Sun, which defines the length of a year. This orbital period is influenced by gravitational forces and the elliptical shape of Earth's orbit, as described by Kepler's laws of planetary motion.


What planets length of the day is 9 hours?

Mercury.

How many ways do planets move?

Planets move in a few primary ways: rotation on their axis, which results in day and night cycles; revolution around a star, like the Sun, which determines their year length; and orbital motion within a solar system, influenced by gravitational forces. Additionally, planets may have other motions, such as precession or tidal forces, affecting their orbits.


What is the length of time it takes planetary objects to revolve around the sun?

Typically, this length of time is called a "year". Each planet's year is a different length than that of the other planets and increases as the planet is further from the Sun.


What determines the length of the planets year?

The eight planets are in order in their various places. If a planet is closer to the Sun, it will have a shorter orbit and therefore will take less time to complete its orbit. If a planet is farther away from the Sun, it will have a longer orbit and will take more time to complete its orbit. For example, Earth, the third planet from the Sun and takes just a year to revolutionize it, but since Uranus, the seventh planet, is farther away from the Sun, it will take 81 years to complete its orbit.
