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 .
Triton's southern polar cap and dark plume streaks. 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 ...
Triton's geology is vigorous, and has been and continues to be influenced by its unusual history of capture, high internal heat, and its thin but significant atmosphere. Nearly nothing was known of Triton's geology until the Voyager 2 spacecraft flew by the Neptune system in 1989, marking the first and only up-close observations of the moon as ...
Triton has a tenuous but well-structured and global nitrogen atmosphere, [47] with trace amounts of carbon monoxide and small amounts of methane near its surface. [48] [49] [12] Like Pluto's atmosphere, the atmosphere of Triton is thought to result from the evaporation of nitrogen from its surface. [27]
Titan has a denser atmosphere than Earth, with a surface pressure of 1.4 bar, while Triton has a relatively thinner atmosphere of 14 μbar; Titan and Triton are the only known moons to have atmospheres significant enough to drive weather and climate processes. [25]
This GOES-16 GeoColor satellite image taken Friday, Oct. 9, 2020, at 10:00 a.m. EDT, and provided by NOAA, shows Hurricane Delta over the Gulf of Mexico. (NOAA via AP) Sometimes it seems that the ...
Secondly, they both have atypically small semi-major axes, with Triton's being over an order of magnitude smaller than those of all other known irregular moons. Thirdly, they both have unusual orbital eccentricities: Nereid has one of the most eccentric orbits of any known irregular satellite, and Triton's orbit is a nearly perfect circle.
Triton, Neptune's largest moon, has a tenuous nitrogen atmosphere with small amounts of methane. Tritonian atmospheric pressure is about 1Pa. The surface temperature is at least 35.6 K, with the nitrogen atmosphere in equilibrium with nitrogen ice on Triton's surface. Triton has increased in absolute temperature by 5% since 1989 to 1998.
