What else can I help you with?
Why does the length of the day and night vary from planet to planet?
Because of the difference in speed of rotation of each planet.
What determines the length of an entire year on a planet?
The time it takes for any given planet to make one complete revolution around its sun determines the length of its year.
What movement of the planet makes one day as a unit of time?
It is the rotation of the planet one complete revolution that determines the length of a day.
What is period of rotation and revolution of Venus?
Venus' period of rotation is 243 Earth days. Its period of revolution is 224. 7 Earth days. The revolution period is the length of a year in Earth days on Venus. This planet is a terrestrial planet.
What is the length of revolution for the dwarf planet Haumea?
In time 285 yearsIn distance 1.67 billion kilometers
What is the difference between a planet's period of rotation and period of revolution?
All planets in our solar system vary in the time it takes them to complete a revolution. This is due to their differing distances from the sun. As far as rotation goes, the time varies from nine hours and fifty minutes for Jupiter to 244 days for Venus to make a like rotation.
What is the length of revolution for the dwarf planet Makemake?
In time 310 yearsIn distance covered 1.8 billion kilometers.
What is the length of revolution for the dwarf planet Eris?
The time Eris takes to orbit the Sun is about 557 years.The length of Eris's orbit around the Sun is about 60 billion kilometers
Why do planets differ in their length of revolution around the sun?
because each planet are different lengths away from the sun so if would then take longer periods of revolution around the sun
How are planets distances from the sun generally related to the length of their year and their period of revolution?
The distance a planet is from the Sun relates to the length of the planet's year because it determines the time it takes for the planet to complete one revolution around the Sun. A planet's "year" is the time taken to orbit the Sun once. The further a planet is from the Sun, the further it must travel to complete an orbit. Also, a planet moves more slowly when it is further from the Sun. The mathematical equation for all this is given by Kepler's "Third Law of Planetary Motion". Earth takes about 365.25 days to complete a revolution. So, our year is 365 days with 366 days in a "leap year".

Why does the length of a day and year vary from planet to planet?
Some planets rotate faster or than others. Also the planets take different times to orbit the Sun.
