Unlike Callisto, Ganymede has an iron-rich core and a permanent magnetic field that is strong enough to create its own magnetosphere and auroras. (Note that Jupiter's magnetosphere is far from spherical -- it extends "only" a few million kilometers in the direction toward the Sun.) Saturn's magnetic field has north and south poles, like those on a bar magnet, and the field rotates with the planet. Jupiter has the strongest magnetic field of any of the planets in the solar system. And the planet has another big magnetic "south pole" close to the equator the researchers refer to this equatorial patch as a "great blue spot" in their paper, in contrast to the planet's swirling Convection within Earth's iron core also generates our planet's magnetic field, but Earth's field is much more straightforward: mostly positive at one pole, mostly negative at the other, with no particular pattern to the parts that diverge from that.This strange magnetic field on Jupiter is a hint to what's going on inside the planet. Many of these X-ray versions are larger than Earth itself. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Jupiter has a huge magnetic field, much stronger than Earth's. But while the gas giant's south pole is relatively orderly, the planet's north pole has one narrow magnetic hotspot amid more chaotic patches of magnetic field, where positive and negative sections don't have concrete counterparts. On Jupiter and Earth, the magnetic fields are slightly tilted with respect to the from the planets' rotation axes – this tilt is the reason we say compass needles point to "magnetic north" rather than true north.
Which planet has the largest size, volume, and mass?Jupiter revolves and rotates in which direction? If there is a magnetic field, there is certainly a molten iron core and substantial convective currents within the core. (Image credit: Bloxham, Jeremy; Moore, Kimberly (2018)/Figshare NASA's Juno spacecraft has mapped the strong magnetic field at Jupiter, revealing a surprising asymmetry between the northern and southern hemispheres that could lend insight into what's going on within the gas giant.Jupiter hosts the most powerful magnetic field of all the planets in our solar system, cranking out a field "We find that Jupiter's magnetic field is different from all other known planetary magnetic fields," the authors, led by Kimberly Moore of Harvard University, wrote in the paper.

Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. Start studying Jupiter and Saturn. Hubble Space Telescope observations of how Ganymede’s auroras change when interacting with Jupiter’s magnetic field reveal the likely existence of a subsurface ocean about 100 km (60 miles) thick.
