What is Neptune?

Answer 1

Neptune is the 8th planet from the Sun and the outermost major planet in our solar system. Neptune is slightly smaller but more massive (dense) than Uranus.

Neptune is nicknamed the "Ocean Planet" because of its blue color, and no actual liquid water exists as there is on Earth. It is a gas and "ice" giant with a surface covered by crushingly dense clouds of hydrogen and helium. The outer layers are very cold: the temperature at Earth pressures are as low as -200°C (-328 °F). Near the core a water-methane mix exists at thousands of times Earth pressure, and a temperature of over 1000°C (1800°F). The winds in the atmosphere of Neptune can reach up to 1000 miles per hour (1600 kph).

One interesting speculation is that it may "rain diamonds" on Neptune, as methane breaks down into carbon and hydrogen under the heat and pressure near the core.

Neptune is named for the Roman god of the sea.

Answer 2

neptune is very much like Uranus but it is bluer because it has more gas and colder.
Neptune is the eighth planet from the sun in the solar system and is the fourth largest planet by diameter and the third by mass. It has seventeen times the mass of Earth and was named after the Roman god of the sea. It was discoveredSeptember 23,1846

Answer 3

Neptune is the eighth and farthest planet from the sun in our solar system. It is a gas giant, similar to Uranus, and is known for its striking blue color due to the presence of methane in its atmosphere. Neptune has a system of rings and a collection of moons, the largest of which is Triton.
