Contrast Jupiter's magnetosphere with that of Earth and of the other jovian plan

Compared with Earth, its general properties are very similar, except that it is about 20,000 times stronger and it extends 3,000,000 km beyond Jupiter.

Compared with Jovian planets: Saturn, Uranus, & Neptune have smaller & weaker magnetospheres (the fraction of electrically conducting material in interiors is smaller).  Solar wind is weaker farther out, or else their magnetospheres would be even smaller.

Jupiter has the strongest magnetic field by far among the planets. It is 20,000 times stronger than Earth's. Its strong field is able to deflect the solar wind about 40 Jupiter radii in front of Jupiter. The magnetosphere around Saturn is smaller because it has a much thinner layer of metallic hydrogen. Although Uranus and Neptune have no metallic hydrogen, and therefore much weaker magnetic fields generated in their cores, the solar wind is also much weaker at their great distances from the Sun. Therefore, their magnetospheres are larger than they would be if the planets were closer to the Sun. Even with the weaker solar wind, however, these planets have very small magnetospheres.
