Neptune's rings and moons viewed in infrared by the James Webb Space Telescope. Neptune has a planetary ring system, though one much less substantial than that of Saturn and Uranus. [167] The rings may consist of ice particles coated with silicates or carbon-based material, which most likely gives them a reddish hue. [168]
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 ...
The following outline is provided as an overview of and topical guide to Neptune: . Neptune – eighth and farthest known planet from the Sun in the Solar System.In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet.
Neptune was discovered in 1846 and is located 30 times farther from the sun than Earth. The planet's 164-year orbit takes it through some of the darkest and most remote regions of the outer solar ...
Triton, the largest moon of the ice giant planet Neptune, is hypothesized to have been captured from heliocentric orbit. Triton is unusual as it is the only known large moon on a retrograde , highly- inclined orbit; that is, Triton orbits in the opposite direction Neptune rotates, and its orbit is not aligned with Neptune's equatorial plane.
[example needed] The data from Voyager 2 are still the best data available on this planet in most cases. [citation needed] 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 ...
