The Hubble Space Telescope has been used to assemble a time-lapse color movie showing a full 16-hour rotation of Neptune. The Voyager 2 flyby in 1989 revealed strong winds, bright, high-altitude clouds, and two large dark spots attributed to long-lived giant storm systems. Tracking of these features indicated wind speeds as large as 730 miles per hour. The largest dark storm systems, called the "Great Dark Spot", is shown in the image adjacent left. It resembles Jupiter's Great Red Spot (more info). The interior is presumed to contain a rocky core with an icy mantle topped by a deep layer of liquid hydrogen. Voyager 2's instruments detected a complex magnetic field. Like Uranus, the field is tipped with respect to the axis of rotation and offset from the center (the tilt is 50 degrees for Neptune, compared with 60 degrees for Uranus). However, the field is somewhat weaker than for Uranus. As for Uranus, it is speculated that this magnetic field my originate in a conducting shell not far below the clouds, rather than deep in the interior as for Jupiter or the Earth. In that case, the conducting material would not be metallic hydrogen, as for Jupiter, or iron and nickel, as for the Earth. As noted earlier for Uranus, a mixture of water, methane, and ammonia under the right pressure could be responsible

Neptune is the eighth planet from the Sun; the only planet farther from the Sun is Pluto. Every 248 years, Pluto travels inside Neptune's orbit for about a 20 year period, during which it is nearer the Sun than Neptune. Pluto entered Neptune's orbit in January, 1979, and stayed there until March, 1999. The orbit of Neptune, called the blue planet, is 4,504,000,000 kilometers from the the Sun, about 30 times as far from the Sun as the Earth. Neptune's rotation period as it spins on its axis, in earth hours, is 16.11 hours, compared to our 24 hour rotation periods. Neptune's axis is tilted 30 degrees to the Sun's orbit. Neptune moves around the Sun in an elliptical or oval-shaped orbit; its orbit period in earth years is 163.72 years. One season on Neptune lasts for forty years; its south pole is in darkness for forty years, while the north pole is in sunlight for forty years. Being the smallest gas planet, Neptune's diameter of 49,500 km is smaller than Jupiter's and Uranus', but is larger than the Earth's (almost 4 times the Earth's). Neptune's surface is almost identical to Uranus'; a combination of ice and glaciers, rocks and craters make up Neptune's surface with about 15% hydrogen and little helium. Neptune also has great geysers of liquid nitrogen. Neptune has a very solid ground, not like Saturn and Jupiter; these two planets both consist of gases. Neptune's core or center is a region of heavily compressed gases that blend into a central rocky interior. Neptune has a mantle of liquid hydrogen while the atmosphere is a mixture of ammonia, helium, and methane. Neptune is blue because methane in the atmosphere absorbs red wavelengths of light and reflects the blue. The methane freezes in the upper atmosphere and forms an ice cloud which casts a shadow on the clouds below. Neptune is covered by a thick layer of clouds with very strong winds and large hurricane-like storms. Neptune's winds are the fastest in the universe; they can reach speeds up to 2000 km an hour. Neptune's prominent feature is the Great Dark Spot, a large dark oval on its surface which astronomers belive are hurricane storms; it is as big as the Earth. Neptune also has 4 very dark rings, 2 thin and 2 thick, which are made of dark particles that are different in size. Neptune was discovered when astronomers were looking for Uranus; the way they found it was that the gravitational pull of another object, Neptune, was interfering with Uranus' orbit as predicted by astronomers. Neptune has a very strong magnetic field just like Uranus'; it is probably generated by ground water. Neptune has 8 different moons, or natural satellites, 4 of which orbit within the rings; the largest of these moons is Triton which has a surface temperature of about -235 degrees Celsius. It also has a thin atmosphere of methane and nitrogen.

I think you all should stop talking crap and start talking about Neptune. you are making this website suck!! if you don't have anything to say about Neptune then leave. Mass- 17.15 Earth masses. Moons- 8 Size- 8th largest planet. Temperature- at cloud tops, about -216 degrees Celsius. Atmosphere- 74% hydrogen, 25% helium, and 1% methane. Also has clouds and storm systems rotating around it. Wind- Winds of over 1,000 miles per hour travel across Neptune. Gravity- About 110% of the surface gravity on Earth. So if you weighed 100 pounds on Earth, you would way 110 pounds on Neptune. Life- Because of such hectic weather, probably no existence of life. Also the year span would be hard to adapt to. Surface- Very little is known about the surface of Neptune. Thanks for reading, hope you have success, dont be hypocritical.

Neptune looks blue from the outside. It has a dark blue spot on it which is a storm. If you look closer you will see that its atmosphere is made up of thick clouds, ice crystals, hydrogen, helium, methane, and a bit of sulfur. Also It is a very gaseous planet. It has a hard inner core made of metal and rock.

Neptune is the eighth planet from the sun, and is one of the outer gas giants. it has a rocky core, liquid mantel, and gaseous surface. Neptune's surface isn't solid, and is made up of the gasses hydrogen, helium, and methane. methane gives Neptune its blueish color. Neptune is sometimes considered Uranus'stwin due to their similarities in density, mass, and composition. ***(p.s. this isn't a chatroom and kids do go on this sight so answer the question or not, don't post cuss words or jokes. i work for a sight similar to this and those postings are tracked back to the person who posted them.)
