Saturn is further from the sun than is Mars, so it has to travel further to go around the Sun once. As a result it takes Saturn longer to go around the Sun than it takes Mars. Since a year for any planet is the time it takes for it to go around the sun, the year for Saturn is longer than the year for Mars.

∙ 15y agoA year on earth is the time it takes earth to make one complete orbit around the sun. If we apply the same idea to other planets, that is, if we say that the year on another planet is the time it takes that planet to make one complete orbit of the sun, then the years of the planets will all be different. This is because the time it takes a planet to orbit the sun is greater the farther out from the sun we look. Mercury is the planet closest to the sun. It is also the planet with the shortest year. Venus in next closest, and it has a shorter year than earth (or any other planet) except Mercury. And so on, and so on. Different orbital characteristics make for different orbital periods. The farther out you are, the longer your obit takes. The planets closer in have to move faster in orbit because being closer to the sun means the pull of the sun's gravity will be greater up close. The planets must move more quickly when they are closer to the sun so they do not "fall in" and get swallowed. Their increased orbital speeds keeps them in orbit.

∙ 12y agoThe different planets have different lengths of orbits because each planet must strike a "balance" to have an orbit at all. This applies in this and any other solar system. The balance in this case is the pull of the sun's gravity on a planet, and the inertia that keeps a planet moving in its orbit.
The question posed might probably be one of orbital mechanics. Planets farther out from the sun move more slowly, and they carve out large orbits. They take more time to complete an orbit, too. Orbits are essentially eliptical, but the bottom line is that planets have a given mass, and are a given distance from the sun. They also have a given inertia because they were moving when they formed. For a given mass that is a given distance from the sun with a given inertia, there is only one solution to describe the orbital path for that planet. And for bodies farther from the sun, the solution reveals large, orbital pathways. The farther from the sun a body is, the more slowly it will move to stay in orbit, and the farther it will travel in its trek around our local star.

-- the longer it has to travel to cover one revolution ... we learn that from Geometry ... and
-- the slower it moves in its orbit ... we learn that from Gravity.

∙ 10y agoPlanets have orbits at a different distance from the Sun. The planets that are farther from the Sun have to move farther in their orbits. They also move slower, so the combined effect is that they take longer to go once around the Sun.

and different from those of every other planet.

Planets without solar systems are called?
Planets not orbiting a star but instead orbiting the galactic center are referred to as rogue planets, or nomadic or interstellar planets.
Which planet has the most suns orbiting around it?
Planets do not have suns orbiting around them. Suns have planets orbiting around them. The planet in our solar system with the highest number of discovered moons orbiting around it is Jupiter, with over 100.
Where are ExtraSolar planets found?
Extrasolar planets are planets found orbiting stars other then our own.
What other planets have there own planets?
Planets do not have planets of their own. If a large rock is orbiting a planet, it is called a moon.
What happens if the planets stops orbiting the sun?
The planets will fall into the sun and get destroyed.
Do planets take turns orbiting?
No. The planets all orbit the sun at the same time. The planets occupy different orbits at different distances from the sun so they do not affect one another significantly.
Are there ant planets orbiting gemni?
There may be planets orbiting stars in the constellation Gemini, but planets do not orbit whole constellations.
What is a series of planets orbiting a star?
A series of planets orbiting a star is called a Solar System
Planets without solar systems are called?
Planets not orbiting a star but instead orbiting the galactic center are referred to as rogue planets, or nomadic or interstellar planets.
Is our sun the only star that has planets orbiting around it?
No. Other stars have been found to have planets orbiting them.
What planets are there around the Earth?
There are no planets orbiting Earth.
Is it true that Kepler's laws holds only for the six planets known in his time?
No. It holds for other planets, and for any other situation where one objects orbits another - for example, moons orbiting planets, stars orbiting a black hole, etc.
How planets and stats are different?
Planets are large bodies of gas or rock orbiting around a star. Stats graph data, such as who liked what most at a restaurant.
Why planets do not all orbit the sun at the time?
They are all orbiting the Sun, "at" the same time.But they don't complete their individual orbits "in" the same time.This is because they are ...* different sizes; * different distances from the Sun; * travelling at different speeds.
Why does the universe goes around?
As all the planets rotate around the sun at different speads, they are attracted when orbiting the sun.
Do all the planets have smaller planets orbiting them?
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
Where are ExtraSolar planets found?
Extrasolar planets are planets found orbiting stars other then our own.
