Upper Elementary Science - II
3.9 Outer Planet Neptune

The last of the four gas giants, Neptune is the eighth planet from the sun. It was named for the Roman god of the sea. This planet is so far away that it takes about 165 Earth years to complete one orbit around the Sun. We learnt a lot about Neptune when the Voyager II space probe flew by the planet in 1989. Voyager revealed Neptune to be a frozen and stormy world, bluish in color, with the strongest winds in the solar system- up to twelve hundred miles per hour.
