While _ rotation axis is only tilted 29 degrees, its magnetic fields are just as strange as its twin's.

When Cassini entered orbit around Saturn, it caused the planet's orbit to change.

The oblateness of the jovian planets' disks is caused by their .

Jupiter's magnetic field is much stronger than Earth's, and has a magnetic tail that extends beyond the orbit of Saturn.

All four jovian planets are oblate, with larger polar than equatorial diameters.

The Galileo mission put a spacecraft into orbit around Jupiter. Which statement is true?

Compared to Jupiter, Saturn's east- west zonal (band) flow is _ .

Although it is almost the same size as Jupiter, Saturn's gravity is about 2.5 times less, because of Saturn's lower mass and density.

Essentially, the Great Red Spot is

Jupiter's Great Red Spot is similar to a hurricane on Earth except for its size.

Of the jovian planets, which generates the least internal heat?

The rotation of the magnetic fields of the jovian planets is believed to also give us the rotation rate of the planet's core.
