A year is the time it takes Earth to go once around the Sun. Depending on the selected reference point, there are slightly different values for the year. A sidereal year uses the background stars as a reference point. In a way, this is the real period of revolution. However, in practice, the tropical year is normally used, which is what affects the seasons. The difference between these two definitions of year is due to the Earth's axis gradually changing its direction in space. For more information, read about the Earth's precession.

How many earth Years is one Saturn Year?
The length of one sidereal Earth year is 3.39% the length of one sidereal Saturn year. In other words, the length of one sidereal Saturn year is 29.5 times the length of one sidereal Earth year. (A sidereal year is the time between alignments of the sun, the planet, and a distant fixed star.)
What is Mars period?
The length of a Martian day is equal to 1.027491204 Earth days. The length of one sidereal Martian year is equal to 1.880791 sidereal Earth years.
What planet has the greatest similarity between the length of its day and the length of its year?
Venus. The "day" (rotation period or sidereal day) is longer than the year! Venus Sidereal day: 243 Earth days. Venus Year: 224.7 Earth days.
What fractions of 1 day is?
1 day is 1/365.25636 of a sidereal year.
What is the Period of difference between a solar and a lunar year?

How much larger in earth days is a year on mars than on earth?
321.7 sidereal days.
What planet has the second shortest day?
Mercury has the 2nd longest "sidereal day" with a sidereal rotation period of 58.646 Earth days. The longest "sidereal day" day is Venus, with a sidereal rotation period of 243.018 Earth daysIf you use the "solar day" as your definition of "day", the order is reversed. Mercury then has the longest day and Venus has the second longest day.
What is earths sidereal period?

What's the difference between a sidereal year and a synodic year?
A sidereal year is measured based on the planet's position in space relative to the background stars. A synodic year is measured based on the planet's position relative to the star it rotates around (i.e. the sun) Here's an image that is pretty helpful in visualizing.
