Neptune is the eight planet and was discovered by astronomers John Couch Adams and Urbain Jean LeVerrier. It is slightly smaller than Uranus, and spin once every 19.2 hours. Neptune is about 2,799 million miles from the Sun. It takes about 165 Earth years to complete a single orbit. Neptune can be seen through a telescope. It appears in the form of a blueish circle. This image was taken by Voyager 2 in 1989.

Neptune’s Atmosphere is made up of Methane gas on its surface which helps to give it its blueish appearance. It also contains ammonia and helium. Beneath its dense blanket of gases, the planet is thought to have an outer layer of liquid hydrogen.

Voyager 2 observed long, swirling clouds swirling around Neptune blown by winds of up to 1,243 miles per hour. It also saw dark spots with the largest named the Great Dark Spot which looks like the size of the earth. Voyager 2 scientists named the little cloud below it the Scooter because it raced around the planet every 16 hours.

Neptune has fourteen moons with the largest of them named Triton and Nereid. Triton is bigger than the planet Pluto. Most moons orbit their planets the same direction as the planet spins. Triton, however travels in the opposite direction as shown below. Triton’s surface is bright and smooth. It has some dark streaks over it and pink ice around its south pole. Triton has a thin atmosphere of Nitrogen and Methane as similar to Saturn.

Mystery Storm

Despite its great distance from the sun and lower energy input, Neptune’s winds are three times stronger than Jupiter’s and nine times stronger than Earth’s.

In 1989, Voyager 2 tracked a large, oval, dark storm in Neptune’s southern hemisphere. This hurricane-like Great Dark Spot was observed to be large enough to contain the entire Earth. It spun counterclockwise and moved westward at almost 750 miles (1,200 kilometers) per hour. (Subsequent images from the Hubble Space Telescope showed no sign of the Great Dark Spot photographed by Voyager. A comparable spot appeared in 1994 in Neptune’s northern hemisphere but had disappeared by 1997.) Voyager 2 also photographed clouds casting shadows on a lower cloud deck, enabling scientists to visually measure the altitude differences between the upper and lower cloud decks.

The planet has six rings of varying thicknesses, confirmed by Voyager 2’s observations in 1989. Neptune’s rings are believed to be relatively young and relatively short-lived.

Neptune does not have a solid surface, and the atmosphere consists primarily of hydrogen, helium, and methane, which gives the planet its blue color

Neptune sits at the frigid edge of the solar system. Its surrounding space features faint rings system, a family of 14 moons, and a strong magnetic field that influence the icy debris of the outer solar system.

The immediate space around Neptune is dominated by several unique characteristics:

• The Ring System: Neptune has six distinct rings. They are mostly composed of microscopic dusty materials and are circular in nature.
• The Moons: The planet is orbited by 16 natural satellites. The largest by far is Triton, a frozen world with active nitrogen geysers. Triton travels in a retrograde orbit (backward compared to Neptune’s rotation), which is slowly causing it to spiral inward. Scientists believe Triton will eventually be ripped apart by Neptune’s gravity, which may form an even larger ring system in the distant future.
• Extreme Weather: The space environment immediately above Neptune’s atmosphere is highly dynamic. Neptune generates its own internal heat, which drives the fastest winds in the solar system—up to 1,300 mph (2,100 km/h)—and fuels colossal, Earth-sized hurricanes.
• Complex Magnetosphere: Neptune’s magnetic field is tilted about 47 degrees from its rotational axis, causing it to wobble wildly as the planet spins.
