Реферат: Uranus and Neptune
The seventh planet from the sun is much like its gaseous neighbors, witha cloudy surface, rapid winds, and a small rocky core.
Uranus: personification of heaven inancient myth
Perhaps because of a collision with a large object long ago, Uranus orbitsat an extreme tilt of 98 degrees — sort of on its side. This causes one poleto point toward the sun for decades, giving the planet strange seasons.
Uranus has numerous satellites and a faint set of rings. If all the possiblesatellites being studied are confirmed, Uranus would have 16 regular and fiveirregular moons, making it the most populated planetary satellite systemknown. Saturn is known to have 18 satellites (there may be more, but they havenot been well-documented).
Uranus was thought to be a star until William Herschel discovered in 1781 that it orbited the Sun.
The eighth planet from the Sun — well, some of the time it'seighth, but more on that later — has a rocky core surrounded by ice,hydrogen, helium and methane.Like the other gas planets, Neptune has rapidly swirlingwinds, but it is thought to contain a deep ocean of water. Its quick rotationfuels fierce winds and myriad storm systems. The planet has a faint set ofrings and 8 known moons.
Because of Pluto's strange orbit, Neptune is sometimes the most distantplanet from the Sun. Since 1979, Neptune was the ninth planet from the Sun. OnFebruary 11, 1999, it crossed Pluto's path and once again become the eighthplanet from the Sun, where will remain for 228 years.

Neptune was discovered in 1846 after mathematical calculations ofUranus' movements predicted the existence of another large body.
