What is the length of time a planet takes to orbit the sun?

Answer 1

1 year. The Earth takes 1 Earth year, Mars 1 Mars year, Venus 1 Venus year, etc.

Here's the answer in detail using approximate numbers :

Mercury 88 Earth days.

Venus 225 Earth days

Earth 365 Earth days

Mars 687 Earth days

Jupiter 11.9 Earth years

Saturn 29.5 Earth years

Uranus 84 Earth years

Neptune 165 Earth years

Answer 2

It depends on how close that planet is to the sun. At closer distances, the planets move more quickly where the gravity from the star is stronger, they also have a shorter path to complete. At further distances, the planets have a lower tangential velocity, they move along more slowly and have much further to travel, so take longer to complete one orbit.

There is a relationship between the planets distance from the sun and the time taken for one orbit (planets year), described in Keplars third law. The square root of the time taken to orbit the sun is proportional to the cube of the average distance between the sun.

Answer 3

The time a planet takes to orbit the sun, known as its orbital period, varies depending on the planet. For example, Earth takes about 365 days to orbit the sun, while Mercury takes only about 88 days, and Neptune takes about 165 years.

Answer 4

365.2 days
