		The atmosphere of Neptune is composed primarily of hydrogen, with a smaller proportion of helium.

	Natural Satellite - MSN Encarta
		The motion of most of the solar system's natural satellites about their planets is direct: west to east, in the same direction as the rotation of their planets.
		Several small satellites of the large outer planets, however, revolve in the retrograde direction: east to west, opposite the direction of the rotation of their planets.
		These retrograde satellites tend to orbit far from their primaries and were probably captured by the planets' gravitational fields some time after the formation of the solar system.

		Had Neptune been moving at its regular/average speed when Galileo first observed it in 1612 and 1613, he would have most likely realized that it was a planet and not a fixed star due to Neptune's relatively rapid normal motion along the ecliptic compared to the extremely slow motion of the fixed stars.

		Neptune's temperature at its cloud tops are usually close to â’210â (â’346Â°F), one of the coldest in the solar system, due to its long distance from the sun.
		However, the issue is now being re-evaluated by historians with the rediscovery in 1998 of the "Neptune papers"?title=(historical documents from the Royal Greenwich Observatory), which had apparently been misappropriated by astronomer Olin Eggen for nearly three decades and were only rediscovered (in his possession) immediately after his death.
		Shortly after its discovery, Neptune was referred to simply as "the planet exterior to Uranus"?title=or as "Le Verrier's planet."?title=The first suggestion for a name came from Galle.
