Some planets rotate faster or than others.

Also the planets take different times to orbit the Sun.

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.


Is this true or false the length of a planet's year is determined by how fast it spins?

False, the speed it spins on it's axis determinds the length of day. The speed it rotates the sun determinds the length of it's year.


How does the movement of the earth affect the length of its day and its year?

the tilt of the planet


What does the term day mean for a planet?

In general terms a day for a planet is the time taken for the planet to make on rotation on its own axis. Likewise a year for a planet is the time taken for the planet to make one orbit (rotation round) its primary star. Where a planet is tidally locked to its primary, the day length and the year length will be the same, such that the planet keeps one face permanently towards it primary (like the Moon does to the Earth).


How many hrs in the shortest day of the year?

That depends where you are on the planet. the length of day is shorter the further away from the equator you are.


What planet has the greatest similarity between the length of its day and the length of its year?

Venus. The "day" (rotation period or sidereal day) is longer than the year! Venus Sidereal day: 243 Earth days. Venus Year: 224.7 Earth days.


Why does the length of day vary from one planet to another?

Because different planets have different diameters and spin at different rates.


What planet length in day is close to the length of earths day?

Mars.


What planet's length of its day is close to the length of Earth's day?

Mars


Which planet's day is closest in length to its year?

The planet Mercury has a day that is almost the same length as its year. Mercury's rotation period is about 59 Earth days, which is very close to its orbital period around the Sun of about 88 Earth days. This means that one day on Mercury is almost as long as one year on Mercury.


Does each planet have the same length of day?

No


Is there a similar relationship between distance from the sun and the length of a day of a planet?

No because a day is how long it spins on it's axis not around the sun. But it kinda has a relationship to how long a year is on a planet. Because the farther away it is the bigger it's revolution around the sun is but it just depends on how fast it moves.
