The length of a year is determined by the Earth's orbital motion around the Sun. Specifically, it takes approximately 365.25 days for the Earth to complete one full revolution around the Sun, which defines the length of a year. This orbital period is influenced by gravitational forces and the elliptical shape of Earth's orbit, as described by Kepler's laws of planetary motion.
Time = distance3/2Kepler's 3rd Law of Planetary Motion gives this relationship:The cube of the average distance from the Sun is proportional to the square ofthe period of revolution (year).So: (Distance)3 is proportional to (year)2
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".

It's when the earth makes a full rotation around the sun.
distance from a source of light and how long it takes to orbit that source
It depends which planet you are on. On Earth an planetary year is 365 +/- days. On Saturn a single year is almost 30 earth years.
The time it takes for any given planet to make one complete revolution around its sun determines the length of its year.
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.

A planetary year is the amount of time it takes a planet to orbit the Sun. A planetary year on Earth is 365.26 days.
The Earth's motion around the Sun is what determines a year. This motion is known as revolution, taking approximately 365.25 days to complete one orbit, which is why we have a leap year every 4 years to account for the extra quarter of a day.
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. http:/wwwzperiodzenchantedlearningzperiodzcom/subjects/astronomy/planets -------------------------------------------------------------------------------------- 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).
The time it takes to go around its solar systems sun.
The motion of the Earth revolving around the Sun gives us one year. This revolution takes approximately 365.25 days to complete, resulting in the length of a year.
Mercury is the closest planet to the Sun. According to Kepler's law of planetary motion, the nearer a planet is to the sun, the faster it orbits the Sun.
