The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...
Today, Mars does not have a global magnetic field. However, Mars did power an early dynamo that produced a strong magnetic field 4 billion years ago, comparable to Earth's present surface field . After the early dynamo ceased, a weak late dynamo was reactivated (or persisted up to) ~3.8 billion years ago.
The magnetosphere contains charged particles that are trapped from the stellar wind, which then move along these field lines. As the star rotates, the magnetosphere rotates with it, dragging along the charged particles. [13] As stars emit matter with a stellar wind from the photosphere, the magnetosphere creates a torque on the ejected matter.
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 .
The heliosphere is the magnetosphere, astrosphere, and outermost atmospheric layer of the Sun.It takes the shape of a vast, tailed bubble-like region of space.In plasma physics terms, it is the cavity formed by the Sun in the surrounding interstellar medium.
A schematic illustrating the relationship between motion of conducting fluid, organized into rolls by the Coriolis force, and the magnetic field the motion generates. [53] The Earth and most of the planets in the Solar System, as well as the Sun and other stars, all generate magnetic fields through the motion of electrically conducting fluids. [54]
Generated by the churning molten metals in Earth’s core, the magnetosphere shields the planet from harmful solar radiation and keeps solar winds from stripping away Earth’s atmosphere.
Mercury's magnetic field is approximately a magnetic dipole, apparently global, [8] on the planet of Mercury. [9] Data from Mariner 10 led to its discovery in 1974; the spacecraft measured the field's strength as 1.1% that of Earth's magnetic field. [10] The origin of the magnetic field can be explained by dynamo theory. [11]
