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.


How do you work out the length of 1 year for each planet?

Take the length of the planet's orbit, divide it by the speed at which the planet is orbiting and VOILA! The "year."


What determines a planet's length of a month?

The concept of a "month" doesn't really apply to any planet except the Earth. On Earth the month is closely connected to the Phases of our Moon. A month is not like a "day" or a "year" which depend on times of rotation and revolution of a 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.


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.


What is the length of a year on the planet ngc 3079?

NGC 3079 is a galaxy, not a planet.


How are the 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".

How are the surface temp and length of year on a planet related to the planet's distance from the sun?

As a general rule, the surface temp will go down and the length of the planet's "year" will increase the farther it is from the sun. There are exceptions, but that is the general rule.


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.


What is the length of one year on planet mars?

The length of year on Mars is 686.98 Earth days or 1.88 Earth years.
