	Neptune - Wikipedia, the free encyclopedia
		Neptune's atmosphere has the highest wind speeds in the solar system, up to 2000 km/h, thought to be powered by this flow of internal heat.
		Neptune also resembles Uranus in its magnetosphere, with a magnetic field strongly tilted relative to its rotational axis at 47° and offset at least 0.55 radii (about 13,500 kilometres) from the planet's physical centre.
		Neptune is the intended destination of the mining ship Red Dwarf (1988–) in the books based on the BBC sitcom of that name, but an accident on board sends it into deep space instead.

		Gould, Report to the Smithsoman Institution on the History of the Discovery of Neptune, published by the Smithsonian Institution (Washington, 1850), is the most complete and detailed history of all the circumstances connected with the discovery, and with the early investiga-ions on the orbit of the planet, that has been published.

		Neptune, the eighth planet from the Sun, is known for its weird and violent weather.
		Similarly, Neptune is inclined at a 29-degree angle and the northern and southern hemispheres alternate in their positions relative to the Sun.
		While Neptune has an internal heat source that may also contribute to the planet's apparent seasonal variations and blustery weather, when that is combined with the amount of solar radiation the planet receives, the total is so small that it is hard to understand the dynamic nature of Neptune's atmosphere.

		Neptune is the fourth and outermost of the gas giant planets.
		Because Neptune radiates about twice as much energy as it receives from the dim and distant sun, the mechanism that drives its dynamic weather systems must be very different from that of Earth.
		It is also the only large moon in the solar system that orbits "backwards" around its planet, leading scientists to believe that Triton formed independently of Neptune in the outer solar system and was later "captured" by the planet's gravity.

	Neptune
		Neptune is the eighth planet from the Sun, except when Pluto's eccentric orbit takes it inside Neptune's orbit (for example, in the period 1979 to 1999).
		As with the other Jovian planets, the real rotation period is determined from measurements of the magnetic field, because if it is measured from the cloud motions, the rotation contributed by winds would be superimposed to the internal rotation, thus yielding a wrong measurement of the true rotation period.
