The length of a year, for any planet, is the amount of time that it takes for that planet to complete one orbit of the sun. That, in turn, depends only upon the distance of that planet from the sun. The closer the planet is to the sun, the shorter the year. The farther the planet is from the sun, the longer the year. It takes a certain amount of orbital speed to counteract the gravitational attraction of the sun. And similarly, if a planet is moving faster in its orbit, there will be correspondingly more centrifugal force, causing the planet to move farther from the sun. Orbital mechanics makes it all work out.

What causes the length of the year in the Gregorian calendar?
what causes the length of the year in the gregorian calender
What is the relationship between a planet's distance fromm the sun and the length of its year?
The farther out, the longer the year.
Which planet has 88 days long?
Mercury has a year of length 88 Earth days.
What is one orbit of the sun by a planet is called?
A year. Each planet in a solar system has a year of different length, equal to the time it takes for one complete orbit around its sun.
Is the year on other planet same as on the earth?
A year is a measure of the time it takes a planet to make one complete circle (circuit) around the Sun. Each planet in our Solar system has a different length year. To make things simple, astronomers can use the number of Earth years a planet takes to orbit the Sun once. Everyone understands time expressed in Earth days.
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 is the length of a year on the planet ngc 3079?
NGC 3079 is a galaxy, not a planet.
What planet has a length of year closest to ours?
mars
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 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.
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.
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 would be affected if a planet orbits the sun faster or slower?
The length of the planet's year would be affected.
How does the movement of the earth affect the length of its day and its year?
the tilt of the planet
What is the length of year for planet mercury?
It is approx 88 Earth-days.
What determine the length of a year on a planet?
The length of time it takes to make a complete orbit around the sun.
