A year on another planet is determined by its orbital period around the sun. For example, a year on Mercury is about 88 Earth days, while a year on Mars is about 687 Earth days. The length of a year on a planet depends on its distance from the sun and how fast it orbits.

How long does it take the planets to spin on their axis?
That depends on which solar system and planet you are asking about - we now know for planets orbiting other stars.
How long ago were the planets made?
Planets in our solar system formed about 4.5 billion years ago through a process called accretion, where gravitational forces pulled together particles in a spinning disk of gas and dust around the young Sun. This formation period occurred during the early stages of the solar system's evolution.
How long has Mars been in space?
Mars has been in space since it formed approximately 4.6 billion years ago. It orbits the Sun just like Earth and other planets in our solar system.
Is mars related to any of the other planets?
Mars is related to the other planets in our solar system in that it orbits the Sun like all the other planets. It is neighbors with Earth, being the fourth planet from the Sun. However, each planet has its own unique characteristics and attributes.
What do scientist believe happened 4.6 billion years ago?
Scientists believe that the Earth and other planets in our solar system formed about 4.6 billion years ago from a disk of dust and gas surrounding the young sun. This process, known as accretion, involved the gradual gathering of particles to form the planets.
How long are the planets years?
Uranuses year is 84.3 Earth years
How long have the planets exist?
The planets in our Solar System have existed pretty much as long as the Solar System - about 4.6 billion years. Planets in other, older, solar systems may have existed quite a bit longer - almost as long as the Universe (which is 13.8 billion years old).
How long planets live?
From 1 to 54.72 billion years
How long does it take to travel get to the planet Uranus from the earth?
Voyager took 9 years using a favourable positioning of other planets on the way there.
How long does Saturn take to orbit the planets in the solar system?
Saturn orbits the Sun like the other planets, it does not orbit anything else. One orbit for Saturn takes 29.4571 Earth years.
Age of earth and other planets?
It is estimated that the Solar System is 4.6 billion years old including Earth and the other planets.
How long does it take the first 5 planets to orbit the sun?
This is how long it takes the first 5 planets to orbit the Sun. Mercury: 0.2 years Venus:0.6 years Earth: 1 year Mars: 2 years
Is there life in other planets other than earth?
noones quite sure yet about if there is life on other planets because there is just no scientific proof of that yet. It would take to long to trave to other planets outside of our solar system because they can be light years away. However when we develope a way to reach the speed of light im sure we'll find out
Why is the sun bigger than the other planets?
the sun is bigger than any other planets because millions of years ago meteorites smashed together to make the sun and to any other planets that did not happen
Does the other planets go around the sun?
Our nine planets orbit around the Sun. Other planets that are light-years away orbit around their suns (A sun is just a large star with planets). Hope this helped!
Why light-years are used to measure distances in the universe?
because it is the fastest way to measure in very long distances for example earth to other far away planets
How long ago was the first form of earth?
We believe that our solar system, including the Sun, Earth and all the other planets, formed about 4.5 billion years ago
