A year is the amount of time it takes for a planet to orbit the Sun. If Earth is 1 astronomical unit (AU) away from the Sun, and Neptune is 30 astronomical units (AU) away from the Sun, how does the length of a year on Neptune compare to a year on Earth?

 

• A year is the same amount of time for all planets.

   

• A year on Neptune is shorter than on Earth, since Neptune is bigger and orbits the Sun faster.

   

• A year on Earth is shorter than a year on Neptune because Earth is closer to the Sun.

   

• A year on Earth is shorter than a year on Neptune because Earth is smaller than Neptune.
