I would define a "planetary year" as the time it takes to make one complete orbit around the sun.
The farther from the sun you go the farther the distance one orbit is (larger radius = larger circumference). The length of the planetary year depends upon the distance from the sun and the orbital speed of the planet.
This website has some handy information about the planets in our solar system.

It should be noted however that some farther away planets have shorter planetary years than earth and some closer planets have longer planetary years (due to orbital speed).
What else can I help you with?
When does a planet move slowest in its orbit?
A planet moves slowest in its orbit when it is farthest away from the body it is orbiting, which is known as its aphelion. This is due to Kepler's second law of planetary motion, which states that a planet will move slower when it is farther from the body it orbits.
When does a planet move fast or slow?
A planet in an elliptical (oval) orbit will move faster as it gets to its closest point to its sun, and slow down as it reaches its furthest point. A planet with a truly circular orbit will have a constant speed.
Is the sun near the earth planet?
The sun is very near to The Planet Earth because Earth is the third planet from the sun.
What happens when you turn the coarse-adjustment knob forward?
If you turn the knob away from you, it will come closer to the slide. If you turn the knob towards you, it will move away from the slide/moves up.

What happens to the length of planet year as you move away from the sun?
The more distant the orbit, the longer the year.
What happens if the speed around the sun decreases or increases?
If the speed around the sun decreases, the orbit will become more elongated and the planet will move farther away from the sun. If the speed increases, the orbit will become more circular and the planet will move closer to the sun. This change in speed can affect the length of the planet's year and the temperatures experienced.
What happens to your mass as you move from planet to planet?
Your mass does not change. Your weight, however, changes in proportion to the gravity of each planet.
What happens to the length of day as you move north of equator?
They become shorter.
What happens to the length of day as you move north of the equator?
They become shorter.
What happens if you move away from the moon?
You will becomea capsicum!! :o
What happens when Pluto and Eris move further away from the Sun?
They get colder
What happens to the land as you move west of the Mississippi?
It bleepin goes away
What happens to the shadow as this light source moves?
As you move farther away your shadow get bigger and goes away
What happens to the temperature of the planet as you move away from the sun?
The temperature of planets can vary depending on the path of their orbit around the sun. The closer the planet is to the sun - such as Mercury - the hotter the planet is. And because that planet is so hot, it actually has no ozone layer. As you gradually get further away from the sun, the colder the planets become. Pluto is the coldest planet (or sub planet) because of how far it is away from the sun. It goes over -260 degrees! Planets in the middle (AKA the Rocky Planets) are ranged from warm to high, going from Venus to Neptune . Also, the biggest planet it's possible to stand on is Jupiter, and if you stood on it, you would weigh twice as much because of the amount of Gravity on there.
Why does a planet not move away from its path?
Because gravity is counteracting centrifugal force, holding it in orbit.
What happens to your shadow when you move away from light?
Your shadow will become longer and less defined as you move away from the light source. If you move further away, your shadow may eventually disappear completely depending on the distance from the light source.
