What are some prominent features of Neptune?

Neptune is a dark blue gas giant in the outer solar system. He turns around 30 AU (the far-sun's distance) from the Sun and makes a revolution every 165 years. Since Pluto was degraded to the dwarf planet in 2006, Neptune has been the farthest planet in the solar system.

Neptune was discovered in 1846 by the French astronomer Urbain Le Verrier, who derived his existence by exploring the Uranus orbit. It was named after the Roman god of the sea, in accordance with all other planets that were named after the ancient gods. Its diameter is slightly smaller than four countries. Like other gas giants, Neptune consists mainly of hydrogen gas. It gets its dark blue color from trace methane from Ikes suspended in its atmosphere. Because its composition is somewhat different from Jupiter and Saturn, along with Uranus is sometimes called an ice giant. Neptune is relevant to the dynamics of the Solar System because its gravitational thrust stabilizes 2. Asteroid belt in outer sunIt rises a system whose Pluto is a member of the Kuiper belt.

Although Neptun is more massive than his sister planet Uranus, it is actually less compact and its core is slightly larger. Unlike Uranus, Neptune has some surface features, the most important of its great dark spot, a long life similar to a large red stain on Jupiter. Its more interesting cloud activity is partially attributed to the fact that Neptune produces its own inner heat, about 2.5 times it receives from the Sun. Another storm on Neptune was named by a scooter and a magician.

Another characteristic that Neptune unique among gas giants is the presence of high -level clouds that throw shadows on an opaque cloud deck down. Neptune is the second coldest planet in the solar system after uranium with -224 ° C (-372 ° F or49 hp) temperatures measured on the tops of the cloud in 1989. Neptune has severalTo small, weak azure rings, which were observed by the Voyager spacecraft, when a flying house was carried out in 1989.
