Description
Neptune is the outermost planet in the Solar System. With a mean diameter of 49,244 kilometers, it is slightly smaller than Uranus. It is thirty times further from the Sun than the Earth is and takes nearly 165 years to complete each orbit. The most striking feature is a huge dark spot, know as the Great Dark Spot, which seems similar to the Great Red Spot on Jupiter. Like Jupiter and Saturn, Neptune gives out more energy than it receive from the Sun and so must be very hot inside. (Strangely, Uranus is an exception and does not seem to emit energy in this way.) Neptune has a ring system and eight moons. Triton, the largest moon, is a fascinating world. It has a very thin atmosphere made up mainly of nitrogen with a small amount of methane. It has volcanoes or geysers on its surface, and at -235°C, it is the coldest known place in the Solar System.

Nice shot! SpaceEngine allows for some amazing renders. If only Neptune were that bright in reality. Anyway, a couple small corrections, if I may. First, Neptune's Great Dark Spot is not very persistent, though whether it completely disappeared, or is simply hidden, is still up for debate; regardless, while Voyager 2 did prominently capture the Great Dark Spot, by the time the Hubble Space Telescope attempted to photograph it again (in 1994), the Great Dark Spot had disappeared from view, only to have another dark spot appear again, several years later, so regardless of what is actually going on in the cloud layers, the cycle is nevertheless rapid. Second, Neptune has fourteen known moons thus far, no longer just eight. Four of the new moons were discovered in 2002, one in 2003, and the latest one in 2013.
Still though, good job!

This is gorgeous. I knew you are good at 3D, but this I love the most so far! Wonderful job!

No it is NOT made of water.

There's no guarantee that in its depth, there is ocean of water in the liquid state.

Not entirely. A large portion is hydrogen and helium mixed with nitrogen and other organic stuff. Neptune and Uranus are both ice planets, but Neptune is bigger and warmer inside, so it has more molten matter under the clouds... They both have rocky cores, as do Jupiter and Saturn.
