Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest.

Dec 14, 2012 · Neptune, the eighth and last planet from the sun, is one of the coldest. But despite its great distance, the planet undergoes seasons much like the Earth, creating warmer spots on the planet.
Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest. Scientists think there might be an ocean of super hot water ...
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.
Neptune orbits our Sun, a star, and is the eighth planet from the Sun at a distance of about 2.8 billion miles (4.5 billion kilometers). ... Most of its mass is a hot ...
4 days ago · Neptune has 14 moons (natural satellites), only two of which had been discovered before the Voyager 2 spacecraft flew past the planet in 1989, and a system of rings, which had been unconfirmed until Voyager’s visit. As is the case for Uranus, most of what astronomers know about Neptune, including its rotation period and the existence and ...

Dark, cold and whipped by supersonic winds, giant Neptune is the eighth and most distant major planet orbiting our Sun. More than 30 times as far from the Sun as Earth, Neptune is not visible to the naked eye. The planet’s blue color comes from methane in its atmosphere, which absorbs red wavelengths of light, but allows blue ones to be ...
