Saturn has relatively weak radiation belts, because energetic particles are absorbed by the moons and particulate material orbiting the planet. [47] The densest (main) radiation belt lies between the inner edge of the Enceladus gas torus at 3.5 R s and the outer edge of the A Ring at 2.3 R s.
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.
Uranus, which orbits almost 20 times further from the sun than Earth does, has 28 known moons and two sets of rings. The Voyager 2 observations had suggested that its two largest moons - Titania ...
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 magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
Red is magnetic north to the east of geographic north; blue is to the west. ... the magnetosphere shields the planet from harmful solar radiation and keeps solar winds ... “It has typically ...
A dynamo is generated by a large iron core that has sunk to a planet's center of mass, has not cooled over the years, an outer core that has not been completely solidified, and circulates around the interior. Before the discovery of its magnetic field in 1974, it was thought that because of Mercury's small size, its core had cooled over the years.
