Neptune's mass of 1.0243 × 10 26 kg [8] is intermediate between Earth and the larger gas giants: it is 17 times that of Earth but just 1/19th that of Jupiter. [g] Its gravity at 1 bar is 11.15 m/s 2, 1.14 times the surface gravity of Earth, [71] and surpassed only by Jupiter. [72] Neptune's equatorial radius of 24,764 km [11] is nearly four ...
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 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 drives ...
The ice giants Uranus and Neptune live up to their name. Although humans have only ever sent one spacecraft (Voyager 2) toward these far-flung worlds, scientists have a pretty good idea that these ...
In the 1990s, it was determined that Uranus and Neptune were a distinct class of giant planet, separate from the other giant planets, Jupiter and Saturn, which are gas giants predominantly composed of hydrogen and helium. [1] Neptune and Uranus are now referred to as ice giants. Lacking well-defined solid surfaces, they are primarily composed ...
Generally, Neptune is depicted as a rich, deep blue. Uranus is usually seen as a pale green or cyan. In fact, however, they are much more similar than we thought.
Pliocene climate became cooler and drier, and seasonal, similar to modern climates. 2.5 to present Quaternary glaciation , with permanent ice on the polar regions , many named stages in different parts of the world
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 ...
