They have different lenghts because of their age!!! :) love marina & paige
If you mean why is a year shorter or longer on other planets, a year is generally defined as the length of time that it takes a planet to make one full orbit around the Sun. Each planet moves at a different rate and is a different distance from our sun, therefore the amount of time differs.
What else can I help you with?
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.
What time is taken by a planet to orbit the sun?
Different planets have different times to orbit the Sun. Mercury takes 88 days. Uranus takes 84 Earth years.
Are there leap years on other planets?
no theres not in my opinion because it has to do with the positioning of the sun. If they do it is very different
How are outer planets different from outer planets?
its not different at all they are just outer planets
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.
Why a mass of 1 kg weighs a different amount if it is taken to different planets?
Different planets have different strengths of gravity.
How come the planets look different?
most planets look different from different minerals in soil different particles in the atmosphere
How are planets different from moon?
Planets circle the sun Moons cirle planets.
What have they found on the planets?
the found different rock on the planets
Are planets different shapes?
No. All planets are spherical.
Why do the planets have years that are different lengths?
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.
How do the inner and outer planets atmosphere different?
the outer planets are gaseous and the inner planets are not
