Exam 8: The Jovian Planets: Giants of the Solar System

William Herschel was the discoverer of Uranus.

Because it has a higher percentage of , Neptune appears even bluer than Uranus.

In keeping with its Greek god, Neptune probably contains a lot of water, in a slushy mantle ocean.

The reason the jovian planets lost very little of their original atmosphere is due to their

Contrast the destinations of the probes dispatched by the Galileo and Cassini missions.

Describe how the motion of Uranus led to the discovery of Neptune.

Their magnetic fields should originate in the planets' _ , but those of Uranus and Neptune don't even come close.

Contrast the Great Red and Great Dark Spots.

Compare and contrast the Galileo and Cassini missions.

All four Jovian magnetic fields are good examples of the dynamo theory, with the magnetic fields aligned well with the planets' rapid rotations.

The Great _ _ Spot of Neptune was striking in 1989, but gone by 1995.

While Saturn is almost as large as Jupiter, its mass is only about of Jupiter's.

How are Jupiter and Saturn similar?

Which three played a role in the finding of Neptune?

Contrast the differential rotations of the four jovian planets. Explain.

Uranus and are very similar in size, mass, and color.

Methane gas absorbs the color , accounting for the colors of Uranus and Neptune.

Uranus' rotation axis is tipped over 98 degrees, so its magnetosphere is tipped over the same amount.

Like the discovery of Uranus, the finding of Neptune was accidental.

We have observed a comet strike Jupiter.
