Is a year 365 days?

Happy 2012 everyone! It's the start of a new year. Have you ever wondered what a year is?

An Earth year is 365 days. It's the time that it takes the Earth to orbit the Sun. Have a look at this video of the Earth orbiting the Sun:

Not all years are 365 days! Each planet takes a different amount of time to orbit the Sun, so the length of each planet's year is different to ours. See if you can match up the planet to the length of year below.
