In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune.
This episode of Launch Box takes kids on an incredible journey to the five farthest planets from the sun: Jupiter, Saturn, Uranus, Neptune and Pluto. These planets and their moons were visited by NASA's Voyager 1 and Voyager 2 and what they found were sights never seen before -- giant hurricanes bigger than Earth, a moon with active volcanoes ...
An annotated picture of some of Neptune's many moons as captured by the James Webb Space Telescope. The bright blue diffraction star is Triton, Neptune's largest moon; while Hippocamp, its smallest regular moon, is too small to be seen. The planet Neptune has 16 known moons, which are named for minor water deities and a water creature in Greek ...
[example needed] The data from Voyager 2 are still the best data available on this planet in most cases.

Based on observations taken with Voyager 2 and since then with the Hubble Space Telescope, Neptune appears to spend somewhat more than half its time with a Great Dark Spot. Little is known about the origins, movement, and disappearance of the dark spots observed on the planet since 1989.
The planet Neptune was mathematically predicted before it was directly observed. With a prediction by Urbain Le Verrier , telescopic observations confirming the existence of a major planet were made on the night of September 23–24, Autumnal Equinox of 1846, [ 1 ] at the Berlin Observatory , by astronomer Johann Gottfried Galle (assisted by ...
