A year is a measure of the time it takes a planet to make one complete circle (circuit) around the Sun. Each planet in our Solar system has a different length year.

To make things simple, astronomers can use the number of Earth years a planet takes to orbit the Sun once. Everyone understands time expressed in Earth days.

Is the year on every planet the same as earth?

No, each planet in our solar system has a different length of year based on its orbital period around the sun. For example, a year on Mars is about 687 Earth days, while a year on Venus is about 225 Earth days.


If 1 Planet X year is the same as 500 earth years and the time proportions are the same as earth's how many earth hours are in a planet X's hours and how many earth days are in a planet X's days?

The ratio will always be the same so the answer will be 500 to both questions


Which planet in the solar system has the same amount of days in a year as earth?

Are years on other planets the same length?

No. Every planet has different length years. The farther a planet is from the sun, the longer year it has. Mercury's year is only 88 of our days. Earth's year is exactly 1 year long. Jupiter's year is about 12 of our years, and Pluto's year is 248 of them.


How does a year on earth differ with other planets?

A year on Earth is longer than it is on two other planets, and shorter than it is on the remaining five. The farther a planet is from the sun, the longer its year is.


What cycle determines a year on a planet?

A "year" on earth turned out to be the period of the earth's orbital revolution around the sun, although the word was invented long before any knowledge of the structure of the solar system or the earth's place in it. By analogy, the same word is typically used to refer to the period of orbital revolution of any other planet.


What planet has a year 248 earth years long?

The dwarf planet Pluto is the planet with a year 248 earth years long.


What planet has a year 280 earth years long?

What planet has a year that is only 88 earth days long?

Mercury, the closest planet to the sun, has an orbital period (year) equal to 88 Earth days.


How long is a year on other planets?

A year on other planets varies depending on the planet's orbit 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 farther a planet is from the sun, the longer its year typically is.


What planet has 29 day year?
