Neptune's atmosphere is faintly blue in the optical spectrum, only slightly more saturated than the blue of Uranus's atmosphere. Early renderings of the two planets greatly exaggerated Neptune's colour contrast "to better reveal the clouds, bands and winds", making it seem deep blue compared to Uranus's off-white.
Triton dominates the Neptunian moon system, with over 99.5% of its total mass. This imbalance may reflect the elimination of many of Neptune's original satellites following Triton's capture. [4][5] Triton (lower left) compared to the Moon (upper left) and Earth (right), to scale. Triton is the seventh-largest moon and sixteenth-largest object ...
In order of distance from Neptune, the regular moons are Naiad, Thalassa, Despina, Galatea, Larissa, Hippocamp, and Proteus. All but the outer two are within Neptune- synchronous orbit (Neptune's rotational period is 0.6713 day or 16 hours [20]) and thus are being tidally decelerated. Naiad, the closest regular moon, is also the second smallest ...
The "Great Dark Spot," a storm in Neptune's atmosphere, and the accompanying bright smudge of clouds are captured by the NASA Voyager 2 spacecraft less than five days before its closest approach ...
The climate of Triton encompasses the atmospheric dynamics, weather, and long-term atmospheric trends of Neptune 's moon Triton. The atmosphere of Triton is rather thin, with a surface pressure of only 1.4 Pa (1.38 × 10 −5 atm) at the time of Voyager 2 ' s flyby, [1]: 873 but heavily variable. Despite its low surface pressure, it still ...
The last time Neptune's rings were seen in ... because it is cloaked in a frozen layer of condensed nitrogen and reflects more sunlight than the planet and its atmosphere. Neptune was discovered ...
The atmosphere of Triton is the layer of gases surrounding Triton. Like the atmospheres of Titan and Pluto, Triton's atmosphere is composed primarily of nitrogen, with smaller amounts of methane and carbon monoxide. It hosts a layer of organic haze extending up to 30 kilometers above its surface and a deck of thin bright clouds at about 4 ...
The geology of Triton encompasses the physical characteristics of the surface, internal structure, and geological history of Neptune 's largest moon Triton. With a mean density of 2.061 g/cm3, [1] Triton is roughly 15-35% water ice by mass; Triton is a differentiated body, with an icy solid crust atop a probable subsurface ocean and a rocky core.
