Neptune is the eighth and farthest known planet from the Sun. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth and slightly more massive, but denser and smaller, than fellow ice giant Uranus.
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 ...
An annotated picture of some of Neptune's many moons as captured by the James Webb Space Telescope. The bright blue diffraction star is Triton, Neptune's largest moon; while Hippocamp, its smallest regular moon, is too small to be seen. The planet Neptune has 16 known moons, which are named for minor water deities and a water creature in Greek ...
That process made the planets, especially Neptune, look too much of a rich blue, however. “Although the familiar Voyager 2 images of Uranus were published in a form closer to ‘true’ colour ...
Astronomers have used telescope data to color-correct Voyager 2 images of Neptune and Uranus, revealing that the planets have a similar greenish blue hue.
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 ...
Discovery of Neptune. New Berlin Observatory at Linden Street, where Neptune was discovered observationally. Neptune as imaged by the Voyager 2 probe in 1989. 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 ...
The rings of Neptune are made of extremely dark material, likely organic compounds processed by radiation, similar to those found in the rings of Uranus. [5] The proportion of dust in the rings (between 20% and 70%) is high, [5] while their optical depth is low to moderate, at less than 0.1. [6] Uniquely, the Adams ring includes five distinct ...
