A planet's sidereal year is the time it takes to complete one full orbit around the Sun relative to fixed stars, while its synodic year is the time it takes for the planet to return to the same position in relation to the Earth and the Sun. The synodic year is generally longer than the sidereal year due to the relative motion of Earth and the planet in their orbits. For example, Earth's sidereal year is about 365.25 days, while its synodic year (the time from one vernal equinox to the next) is also about 365.24 days, but for planets like Mars, the difference is more pronounced. This difference affects how we observe and measure planetary positions from Earth.

How long dose it takes to revolveorbitaround the sun?
It takes Earth approximately 365.25 days to complete one orbit around the Sun, which defines a year. This period is known as a sidereal year. To account for the extra 0.25 days, we add an extra day every four years, creating a leap year. Other planets have different orbital periods depending on their distance from the Sun.
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 would cause the solar day to be shorter than the sidereal day?
The sidereal day of a planet is the time it takes to rotate once on it's axis. The solar day is the time from sunrise to sunset. To see why they are different, let's image a planet that rotates very slowly. Every time it goes around its star once, it also rotates once on its axis. Since it rotates once on its axis per year, there is one sidereal day per year. Now, in order for this to work, one side of the planet must be facing the star at all times. This means that there is no sunrise or sunset, so on this planet, there are zero solar days in a year. Now let's image a planet that rotates twice a year (has two sidereal days a year). At the beginning of the year, a side of that planet is facing the star. Halfway through that year, the planet has rotates once, but is on the other side of the star, so that side of the planet is now facing away from the star. At the end of the year, the planet is back where it started. There has been one sunrise and one sunset, so only one solar day. From this we can see that a planet (as long as it has at least one sidereal day per year) has one more sidereal day per year than solar day per year. There are 365.242 solar days in an Earth year, but there are 366.242 sidereal days in an Earth year.
Why are planets seen in different locations at different times?
Because the planets are closer to us so when we look at the planets we can see them move so the closer an object is to you the easier it is to follow its motion. Hope you could use my answer
Is there any time of the year when all the planets are in line with each other?
No, usually the planets are in different directions. Every few years two or three of them line up.
How many more sidereal months than synodic months are there a year?
1 more sidereal month than synodic month
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.
Why stars seem to move faster than planets in the sky as viewed from earth?
It's because we are going round the Sun and so are all the planets. For that reason the time it takes for a planet to go round the ecliptic and arrive back at the same apparent position - called its synodic period - is longer than a year. Venus and Mars have the longest synodic period because their times to go round once are the closest to 365 days. They take 225 and 687 days to go round but the synodic periods are 584 and 780 days. On the other hand the far-out planets do not move much in a year. Neptune takes 165 years to go round so its synodic period is only a little over 365 days and is 367½ days.
How long is a day and a year on the planet?
A planets day (solar day) is the time it takes to rotate once on its axis relative to the sun, the synodic period. A year on a planet is the time taken for the planet travel once around the sun.
What is the sidereal period?
The Sidereal Period is: 1) The period of revolution of one body around another, with respect to the distant stars. 2) The period of rotation of a body on its axis, with respect to the distant stars. This is often called the "sidereal period of rotation". For example, the Earth's sidereal period of rotation is about 23 hours and 56 minutes. The day is 24 hours because it's based on the rotation of the Earth relative to the position of the Sun in the sky.
What day is earth celebrated on?
April. If you want to be specific, April 22.

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 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 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 fractions of 1 day is?
1 day is 1/365.25636 of a sidereal year.
Are day's year's and season's the same on all planets?
No, they are real different from Earth.
