18 de jun. de 2014 · A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above.
COSMOS - The SAO Encyclopedia of Astronomy › Y. Year. A year is the length of time that it takes for a planet, satellite, or other celestial body to complete one orbit around the Sun (or in the case of extrasolar planets, around their star ). For comparison, the orbital period of the Moon around the Earth is related to the month.
