Full Answer

Neptune and the Earth have more differences than they do similarities. Not only is Neptune's diameter nearly four times larger than the Earth's, it is 30 times further from the Sun. A full pass around the Sun equals one year on Earth. It takes Neptune almost 165 Earth years to orbit the Sun. However, a day on Neptune lasts only a little over 16 hours.

Although Neptune is only four times bigger around than the Earth, it has 17 times the mass. It also differs greatly when it comes to volume. Up to 57 Earths could fit inside Neptune, making this huge planet the fourth largest planet in the solar system.

Additionally, Neptune has no solid surface on which to stand. The surface of the planet is made from silicates and water. Wind speeds on the planet can escalate up to 700 miles per hour, making the surface conditions of the planet extremely harsh.
