As with Uranus, this absorption of red light by atmospheric methane is part of what gives Neptune its faint blue hue, [85] which is more pronounced for Neptune's due to concentrated haze in Uranus's atmosphere. [86] [87] Neptune's atmosphere is subdivided into two main regions: the lower troposphere, where temperature decreases with altitude ...
It is the only moon of Neptune massive enough to be rounded under its own gravity and hosts a thin, hazy atmosphere. Triton orbits Neptune in a retrograde orbit—revolving in the opposite direction to the parent planet's rotation—the only large moon in the Solar System to do so.

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. [a] Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units (4.50 × 10 9 km).
The weather and the upper atmosphere play a critical role in getting the best images. McCarthy says forecasts help him make sure he’s getting outside at the right time and a key component is ...
The movie is composed of natural- and enhanced-color views of Neptune that were assembled from images taken in 14 different colored filters, which allow atmospheric features to be seen above Neptune's methane haze. Neptune is shown in natural color with its largest satellite, Triton, as it orbits the planet. Triton orbits in a "backwards" or ...
Typical winds in the banded equatorial region can possess speeds of around 350 m/s (comparable to the speed of sound at room temperature on Earth [31] viz. 343.6 m/s) while storm systems can have winds reaching up to around 900 m/s, in Neptune's atmosphere. Several large storm systems have been identified, including the Great Dark Spot, a ...
Neptune was discovered just after midnight, [1] after less than an hour of searching and less than 1 degree from the position Le Verrier had predicted, a remarkable match. After two further nights of observations in which its position and movement were verified, Galle replied to Le Verrier with astonishment: "the planet whose place you have ...
