The magnetosphere of Saturn is the cavity created in the flow of the solar wind by the planet's internally generated magnetic field. Discovered in 1979 by the Pioneer 11 spacecraft, Saturn's magnetosphere is the second largest of any planet in the Solar System after Jupiter .

2024年11月5日 · Cassini studied Saturn’s magnetosphere by mapping the magnetic field, studying the flow of excited gases under its influence and observing how it affects Saturn’s auroras. The results have provided powerful insights about how Saturn’s inner workings affect the planet’s atmosphere and the space around it.

Saturn's magnetic field is created as material cycles deep within the planet's fluid interior. Outside Saturn's magnetosphere, a million-mile-per-hour flow of electrically charged particles (electrons and ions) from the sun, called the solar wind, spreads out through the solar system.

2004年6月2日 · Saturn's internal magnetic field is closely aligned with the planet's axis of rotation (within 1 degree). Saturn's magnetosphere appears to be intermediate in nature to those of Earth and Jupiter. As with Jupiter's magnetosphere, the dayside inner magnetosphere is mostly driven by the fast planetary rotation.

2025年1月17日 · Saturn’s inner magnetosphere, like the magnetospheres of Earth and Jupiter, traps a stable population of highly energetic charged particles, mostly protons, traveling in spiral paths along magnetic field lines.

2018年10月10日 · The models are constructed by combining the fields of a simple magnetic dipole, a current sheet (whose intensity is tuned match the scale of the magnetotail), and occasionally a ring current. This is a variation of the simple …

2018年7月27日 · A basic view of Saturn's magnetosphere. Earth's magnetic field creates a 'bubble' around Earth that helps protect our planet from some of the more harmful effects of energetic particles streaming out from the sun in the solar wind.

2003年6月3日 · The rings of Saturn definitely affect the motion of particles in the magnetosphere. Saturn's magnetosphere produces beautiful aurora , as well as strong radio signals and other waves, such as whistler waves.

The Saturn magnetosphere, like the other planetary magnetospheres, is an efficient deflector of the solar wind. The solar wind at Saturn flows more rapidly with respect to the velocity of compressional waves than at Jupiter and the terrestrial planets.

Saturn's magnetosphere appears to be intermediate in nature to those of Earth and Jupiter. As with Jupiter's magnetosphere, the dayside inner magnetosphere is mostly driven by the fast planetary rotation.
