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 also has very low internal heat compared to other giant planets, the cause of which remains unclear. Like the other giant planets, Uranus has a ring system, a magnetosphere, and many natural satellites. The extremely dark ring system reflects only about 2% of the incoming light.
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 .
Such a visit likely would have shown that the Uranus magnetosphere is similar to those of Jupiter, Saturn and Neptune, the solar system's other giant planets, the researchers said.
The planet's magnetosphere, though small enough to fit within Earth, [97] is strong enough to trap solar wind plasma. This contributes to the space weathering of the planet's surface. [104] Observations taken by the Mariner 10 spacecraft detected this low energy plasma in the magnetosphere of the planet's nightside. Bursts of energetic ...
Red is magnetic north to the east of geographic north; blue is to the west. - BGS/UKRI/Wessel, P./W. H. F. Smith ... the magnetosphere shields the planet from harmful solar radiation and keeps ...
An image of the planet Uranus taken by the NASA spacecraft Voyager 2 in 1986. New research using data from the mission shows a solar wind event took place during the flyby, leading to a mystery ...
The Ganymedian magnetosphere has a region of closed field lines located below 30° latitude, where charged particles (electrons and ions) are trapped, creating a kind of radiation belt. [96] The main ion species in the magnetosphere is single ionized oxygen [24] (O +) which fits well with Ganymede's tenuous oxygen atmosphere.
