Neptune, the eighth planet from the sun, is an ice giant known for its striking deep blue color, which is caused by methane in its atmosphere rather than a surface ocean. It is the windiest planet in the solar system, featuring supersonic winds over 1,200 mph that drive massive storms like the Great Dark Spot. Neptune holds a unique place in history as the only planet discovered through mathematical prediction, based on irregularities in the orbit of Uranus, before it was visually confirmed by telescope. While a year on Neptune lasts 165 Earth years, its day is only about 16 hours long.

The planet's largest moon, Triton, is also remarkable. It has a retrograde orbit, meaning it travels backward compared to Neptune's rotation, which strongly suggests it was a dwarf planet captured by Neptune's gravity. Triton is one of the coldest objects in the solar system and features active cryovolcanoes that erupt frozen nitrogen. Neptune itself possesses a wild, lopsided magnetic field that is tilted by 47 degrees and significantly offset from the planet's physical center. This chaotic field is believed to be generated not by a solid core, but by a moving, slushy mantle of super-pressurized water and ammonia.
