Planet Neptune is like Uranus in many ways, but has its own unique features. Because of Pluto's highly elliptical orbit, it is currently the most distant planet from the Sun, at a separation of about 30 Astronomical Units. The full disk of Neptune in shown in the adjacent image Neptune has been particularly challenging to study from the ground because its disk is small and badly blurred by the Earth's atmosphere at that distance. In spite of this, ground-based astronomers had learned a great deal about this planet since its position was first predicted by Adams and Leverrier in 1845. However, our most detailed information about Neptune has come from the Voyager 2 flyby in 1989.
The Planet Neptune is the eighth planet from the sun. It is also known as the Blue Giant. Neptune is the fourth and outermost of the gas giant planets and also has rings. Its atmosphere is mostly hydrogen and helium. In Roman mythology Neptune was the god of the Sea. Planet Neptune Facts: |
