Because as they revolve in their orbits around the sun, every planet averages
a different distance from the sun, and that's how gravity works.

Why do different planets have different length orbits?
Different planets have different orbit lengths because of their distance from the sun. Planets closer to the sun have shorter orbits, and planets farther away have longer orbits.
When planets orbit a star?
When don't they? If a planet is in orbit around a star, it is in continual orbit. Orbital periods (the lengths of time it takes different planets to complete one orbit) are different from planet to planet, and are related to the distances between the planets and their stars.
How is years measured?
A year - is the time taken for a planet to orbit once around the sun.
What causes Mars and Saturn to have years of different lengths?
A year is the time taken for a planet to orbit the sun. Therefore because it takes Mars and Saturn different amounts of time to orbit the sun we consider the length of their years to be different.
What does the earth take One year to do?
It takes one year to complete one revolution around the sun. This is the definition of a year. All planets take one (local) year to do so. Years are of different lengths of time depending on what planet you are referring to. A year on earth is different from a year on a different planet
Do all planets have days and years?
They all have days and years, but they are all of different lengths to days and years on Earth.
Why do different planets have different length orbits?
Different planets have different orbit lengths because of their distance from the sun. Planets closer to the sun have shorter orbits, and planets farther away have longer orbits.
What are the lengths of days on planets?
it varies

Why are the lengths of years different on other planets as on earth?
That happens because they are at different distances. The further-out ones have further to go in their orbits, and also they move more slowly, so the time to go round is proportional to the 1.5 power of the distance.

How may days are there in 10 years and 7 months?
It depends on what month you select, since different months have different lengths.
What causes mars and saurn to have years of different lengths?
Because it takes longer to orbit the sun.
Are there any differences among the planets in the solar system?
The better question would be, are there any similarities? Every planet is ENTIRELY different; different mass, different atmospheres, different orbits, different day lengths; no two are even vaguely alike.
