This field is created by water beneath the surface that measures 4,000°F (2,204°C), water so hot and under so much pressure that it generates an electrical field. Voyager 2 found that Neptune is encircled by at least four very faint rings, much less pronounced than the rings of Saturn, Jupiter, or 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 under Neptune's cold clouds.

4 Ιουν 2019 · Neptune and Uranus have estimated core temperatures of 7273 K and 5255 K respectively. Uranus and Neptune however likely do not have liquid water oceans. The combination of pressure and temperature on both planet results in unsuitable conditions for liquid water oceans.
20 Απρ 2016 · Neptune has a surface, depending on the temperature it will be solid or liquid. Due to the pressure the ocean may be liquid hydrogen rather than water.

Neptune's "surface" can therefore be said to be composed of about 80% hydrogen and 19% helium, with a trace amount of methane. The surface layer is also permeated by roving bands of clouds with...
