# Orbital Periods of the Planets

## How long are years on other planets?

A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above. The precise amount of time in Earth days it takes for each planet to complete its orbit can be seen below.

Mercury: 87.97 days (0.2 years)
Venus : 224.70 days (0.6 years)
Earth: 365.26 days(1 year)
Mars: 686.98 days(1.9 years)
Jupiter: 4,332.82 days (11.9 years)
Saturn: 10,755.70 days (29.5 years)
Uranus: 30,687.15 days (84 years)
Neptune: 60,190.03 days (164.8 years)

AMAZING!!⚡⚡⚡

10. Ian Baillie says:

I still treat Pluto as a planet and I’m sure many others do , I’d like to see this in your list. Hopefully it still takes approximately 248 years to orbit the Sun or have the scientists moved the goalposts on this as well?

11. Hannah D says:

Hey! Thanks for helping me with my schoolwork! I was assigned to research the planet Uranus and this really helped! 😀

1. Hey guys im the best soccer player and i would like to thank lionel messi for being bad

13. ricky savage says:

this does not show each planets length of orbit, in a year as we know them

1. Ian Baillie says:

Ricky, for more in depth factoids about space it’s best to have many sources of reference, then do some cross research try this site http://www.org.northern.edu>uss>docs. Have fun .

2. Ian Baillie says:

Sorry Ricky that should read vss not uss

20. please tell us how long it takes each planet to orbit the sun

1. Michael says:

From up above (that is, if you will scroll up to just above this bunch/list of comments) you should see the duration of years for each planet. I copied and pasted it here. So, after the colon, on what should be the next line is not my writing and I cannot and will not take any credit for it. I hope this helps you:
