ammonium hydrosulfide. 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.
Neptune is the fourth largest planet in the Solar System and the third most massive. [31] Neptune is 17 times the mass of Earth, but just 1 ⁄ 18 the mass of Jupiter. [41] Neptune is a little bit more massive than Uranus, though Neptune is denser and smaller in size than Uranus. [31]
There is evidence that Neptune was seen and recorded by Galileo Galilei in 1613, Jérôme Lalande in 1795, and John Herschel in 1830, but none are known to have recognized it as a planet at the time. [6] These pre-discovery observations were important in accurately determining the orbit of Neptune.
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.
One day on Neptune takes about 16 hours (the time it takes for Neptune to rotate or spin once). And Neptune makes a complete orbit around the Sun (a year in Neptunian time) in about 165 Earth years (60,190 Earth days).

Nov 7, 2024 · Neptune, third most massive planet in the solar system and the eighth and outermost planet from the Sun. Neptune has 14 moons, only two of which were discovered before Voyager 2’s visit in 1989, and a system of rings, which were unconfirmed before Voyager.
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.
The exploration mission revealed that Neptune's atmosphere is very dynamic, even though it receives only three percent of the sunlight that Jupiter receives. Winds on Neptune were found to be the strongest in the Solar System, up to three times stronger than Jupiter's and nine times stronger than the strongest winds on Earth.
Mar 28, 2019 · As the windiest, furthest, and faintest planet in our solar system, Neptune is a fascinating world of superlatives. Learn more about the eighth planet in our solar system. Skip to content
