Neptune

[Lil Danny]

Hi there,
I tried to acces Neptune for link but Neptune won't open. What happened? Anyone know? Please let me know. Thanks

Neptune is the eighth and farthest planet from the Sun in our solar system. It is the fourth largest planet by diameter and the third largest by mass; Neptune is 17 times the mass of Earth and is slightly more massive than its near twin Uranus, which is 14 Earth Masses, but slightly smaller due to its higher density. The planet is named after the Roman god of the sea. Its astronomical symbol (♆, Unicode U+2646) is a stylized version of Poseidon's Trident.

Neptune's atmosphere is primarily composed of hydrogen and helium, with traces of methane that account for the planet's blue appearance. Neptune's blue color is much more vivid than that of Uranus, which has a similar amount of methane, so an unknown component is presumed to cause Neptune's intense color. [1] Neptune also has the strongest winds of any planet in the solar system, with estimates as high as 2,500 km/h or 1,500 mph. At the time of the 1989 Voyager 2 flyby, it had in its southern hemisphere a Great Dark Spot comparable to the Great Red Spot on Jupiter. Neptune's temperature at its cloud tops is usually close to −210¢J (−346¢XF), one of the coldest in the solar system, due to its long distance from the sun. Neptune's center is about 7,000¢J (13,000¢XF), however, hotter than the sun's surface. This is due to extremely hot gases and rock in the center.

Faint azure colored rings have been detected around the blue planet, but are much less substantial than those of Saturn. When these rings were discovered by a team led by Edward Guinan, it was thought that they might not be complete. However, this was disproved by Voyager 2. Neptune possesses thirteen confirmed moons. Neptune's largest moon, Triton, is notable for its retrograde orbit, extreme cold (38K), and extremely tenuous (14 microbar) nitrogen/methane atmosphere.

Discovered on September 23, 1846, Neptune is notable for being the first planet discovered based on mathematical prediction rather than regular observations. Perturbations in the orbit of Uranus led astronomers to deduce Neptune's existence. It has been visited by only one spacecraft, Voyager 2, which flew by the planet on August 25, 1989. In 2003, there was a proposal to NASA's "Vision Missions Studies" to implement a "Neptune Orbiter with Probes" mission that does Cassini-level science without fission-based electric power or propulsion. The work is being done in conjunction with JPL and the California Institute of Technology.[2]

A portion of the dwarf planet Pluto's highly eccentric orbit brings it nearer to the Sun than Neptune, whose orbit is nearly circular. As a result, for approximately 13 to 20 years out of the every 248 (Pluto's orbital period), Neptune lies farther from the Sun than Pluto. The most recent occurrence of this phenomenon began 7 February 1979 and ended 11 February 1999.

Thanks I will put it on Video Forums soon.


Yes, I was Sultanman.....
