The dipole magnetic moment of Neptune is about 2.2 × 10 17 T·m 3 (14 μT·R N 3, where R N is the radius of Neptune). Neptune's magnetic field has a complex geometry that includes relatively large contributions from non-dipolar components, including a strong quadrupole moment that may exceed the dipole moment in strength.
The following outline is provided as an overview of and topical guide to Neptune: . Neptune – eighth and farthest known planet from the Sun in the Solar System.In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet.
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 were made on the night of September 23–24, Autumnal Equinox of 1846, [ 1 ] at the Berlin Observatory , by astronomer Johann Gottfried Galle (assisted by ...

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 ...

2005 CA 79 is a trans-Neptunian object and belongs to the twotinos a mid-sized group of objects locked in a 1:2 mean-motion orbital resonance with the planet Neptune (for every orbit a twotino makes, Neptune orbits twice). These objects are therefore protected from Neptune's scattering effect.
Triton, the largest moon of the ice giant planet Neptune, is hypothesized to have been captured from heliocentric orbit. Triton is unusual as it is the only known large moon on a retrograde , highly- inclined orbit; that is, Triton orbits in the opposite direction Neptune rotates, and its orbit is not aligned with Neptune's equatorial plane.
