A rendering of the magnetic field lines of the magnetosphere of the Earth. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. [1] [2] It is created by a celestial body with an active interior dynamo.
The planet's magnetosphere, though small enough to fit within Earth, [96] is strong enough to trap solar wind plasma. This contributes to the space weathering of the planet's surface. [103] Observations taken by the Mariner 10 spacecraft detected this low energy plasma in the magnetosphere of the planet's nightside. Bursts of energetic ...
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. This results in a transfer of angular momentum from the star to the surrounding space, causing a slowing of the stellar ...
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 .
Ganymede, or Jupiter III, is the largest and most massive natural satellite of Jupiter, and in the Solar System.Despite being the only moon in the Solar System with a substantial magnetic field, it is the largest Solar System object without a substantial atmosphere.
The planet's magnetosphere is highly asymmetric and has many charged particles, which may be the cause of the darkening of its rings and moons. Uranus is visible to the naked eye, but it is very dim and was not classified as a planet until 1781, when it was first observed by William Herschel.
Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun.
This frigid planet, our solar system's third largest, remains a bit of an enigma 243 years later. ... Plasma is a common feature in the magnetosphere of other planets so its low concentration ...
