Question

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?* (25 Points)
A. A year is the same amount of time for all planets.
B. A year on Neptune is shorter than on Earth, since Neptune is bigger and orbits the Sun faster.
OC. A year on Earth is shorter than a year on Neptune because Earth is closer to the Sun.
OD. A year on Earth is shorter than a year on Neptune because Earth is smaller than Neptune.
Option 2

Answer 1

Since Neptune is much farther away from the Sun than Earth, it takes longer for Neptune to complete one orbit around the Sun. Therefore, a year on Neptune is much longer than a year on Earth. A year on Neptune is 165 Earth years.
