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.
3 days ago · Neptune, third most massive planet of the solar system and the eighth and outermost planet from the Sun. Because of its great distance from Earth, it cannot be seen with the unaided eye. With a small telescope, it appears as a tiny, faint blue-green disk. It is designated by the symbol ♆.
Dark, cold, and whipped by supersonic winds, ice giant Neptune is the eighth and most distant planet in our solar system. 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.
