Neptune is the eighth and most distant planet in our solar system. Dark, cold, and whipped by supersonic winds, ice giant Neptune is more than 30 times as far from the Sun as Earth. Neptune is the only planet in our solar system not visible to the naked eye. In 2011 Neptune completed its first 165-year orbit since its discovery in 1846.
20 Απρ 2016 · As a gas giant (or ice giant), Neptune has no solid surface. In fact, the blue-green disc we have all seen in photographs over the years is actually a bit of an illusion.

24 Απρ 2017 · The blue "surface" we see in pictures of Neptune is in fact the top of a permanent cloud cover. Below Neptune's clouds lies an atmosphere of hydrogen, helium and methane, which sits above an icy "mantle" layer.
You can’t land or walk in Neptune because it’s a gas giant with no solid surface. Even the slushy layers of ice mixture would be dense enough to hold you. The only place you could hypothetically find a solid surface would be Neptune’s core.
Neptune is the eighth and farthest known planet from the Sun. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth. Compared to its fellow ice giant Uranus, Neptune is slightly more massive, but denser and smaller.
25 Φεβ 2014 · Neptune may look like a smooth blue marble floating in space, but it's really a large gas planet upon which you cannot stand. The blue "surface" you see through a telescope is the cloud cover that hides the rest of the planet.
