Voyager 2's Discoveries at Uranus and Neptune
- Voyager 2 discovered Uranus's serene, featureless cloud deck, challenging previous assumptions about gas giants' atmospheric dynamics.
- Uranus's magnetic field, tilted at 59 degrees, defied conventional planetary magnetic field models, with poles misaligned unlike Earth's.
- Voyager 2 revealed Uranus's rings, including two newly discovered rings composed of fine dust particles and two shepherd moons.
- Prior to Voyager 2, only five moons were known to orbit Uranus, but the mission discovered 11 more, bringing the total to 16 moons.
- Uranus's five original moons are ice-rock conglomerates, with varying geologic activities and surface characteristics.
- Voyager 2's encounter with Miranda, the closest moon to Uranus, unveiled extensive geological dynamism, including internal melting and icy material upwelling.
- Voyager 2's journey to Neptune showcased the planet's hydrogen-rich atmosphere, extraordinary wind speeds, and the Great Dark Spot storm with winds up to 2,400 km/h.
- Voyager 2's exploration of Neptune also revealed partial ring structures and its largest moon, Triton, with erupting geysers and a pinkish nitrogen ice cap.
