Neptune is 30 times the Earth's distance from the sun. It takes nearly 165 Earth years to complete each solar orbit. Yet a day on Neptune lasts only about 16 hours. You could fit 57 Earth's into Neptune, and its diameter is four times greater than the Earth's. Neptune is denser than Uranus, but bulk-for-bulk far lighter than Earth. Neptune would be just one-fifth as heavy as on Earth.
