What is nepunes surface like?
Neptune’s composition is probably similar to Uranus’: various “ices” and rock with about 15% hydrogen and a little helium. Like Uranus, but unlike Jupiter and Saturn, it may not have a distinct internal layering but rather to be more or less uniform in composition. But there is most likely a small core (about the mass of the Earth) of rocky material. Its atmosphere is mostly hydrogen and helium with a small amount of methane. Neptune’s blue color is largely the result of absorption of red light by methane in the atmosphere but there is some additional as-yet-unidentified chromophore which gives the clouds their rich blue tint. Like a typical gas planet, Neptune has rapid winds confined to bands of latitude and large storms or vortices. Neptune’s winds are the fastest in the solar system, reaching 2000 km/hour.
1) “Like the other gas-giant planets, Neptune’s “surface” is the top of its deep atmosphere. This contains hydrogen (79 percent), helium (18 percent), and methane (3 percent), which gives the planet its blue color. Neptune’s atmosphere has a striped pattern like both Jupiter’s and Saturn’s.” Source and further information: http://www.astronomy.com/asy/default.aspx?c=a&id=1225 2) “Scientists believe that Neptune is made up chiefly of hydrogen, helium, water, and silicates. Silicates are the minerals that make up most of Earth’s rocky crust, though Neptune does not have a solid surface like Earth. Thick clouds cover Neptune’s surface. Its interior begins with a region of heavily compressed gases. Deep in the interior, these gases blend into a liquid layer that surrounds the planet’s central core of rock and ice. The tilt of its axis causes the sun to heat the Neptune’s northern and southern halves alternately, resulting in seasons and temperature changes. Neptune is surrounded by thick l
Neptune’s surface is almost identical to Uranus’; a combination of ice and glaciers, rocks and craters make up Neptune’s surface with about 15% hydrogen and little helium. Neptune also has great geysers of liquid nitrogen. Neptune has a very solid ground, not like Saturn and Jupiter; these two planets both consist of gases. Neptune’s core or center is a region of heavily compressed gases that blend into a central rocky interior. Neptune has a mantle of liquid hydrogen while the atmosphere is a mixture of ammonia, helium, and methane. Neptune is blue because methane in the atmosphere absorbs red wavelengths of light and reflects the blue. The methane freezes in the upper atmosphere and forms an ice cloud which casts a shadow on the clouds below. Neptune is covered by a thick layer of clouds with very strong winds and large hurricane-like storms. Neptune’s winds are the fastest in the universe; they can reach speeds up to 2000 km an hour. Neptune’s prominent feature is the Great Dark Spo
