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 ...
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.
According to Lunine, "oceans" have been defined as "stable, globe-girdling bodies of liquid water." [13] In addition, "Ocean worlds is the label given to objects in the solar system that host stable, globe-girdling bodies of liquid water," in contrast to the terms "'ocean planet' and 'water world', both of which refer to exoplanets (planets orbiting other stars) with substantial mass fractions ...
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 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.
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 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 .
Astronomers have found water in a disc that could be forming planets – potentially helping solve a mystery around how new worlds form.. Researchers had not been able to map how water is ...
