Jovian Planets

How does the mass of Jupiter compare with that of the other planets?

• It is almost as massive as Saturn.

• It is slightly larger and more massive than Saturn.

• It is similar to that of the Earth and Venus.

• It is about a tenth the mass of the Sun.

• It is twice as massive as all other planets combined.

Essentially, the Great Red Spot is:

• always located within 10 degrees of Jupiter's north pole.

• a large cyclonic storm (hurricane).

• traveling north and south across Jupiter's face.

• Neptune's largest atmospheric feature.

• composed primarily of iron oxide.

Saturn's storms are most analogous to:

• carbon dioxide and ethane.

• nitrogen and oxygen.

• methane and ammonia.

• hydrogen sulfide and ammonia.

• hydrogen and helium.

The reason Saturn lost very little of its original atmosphere is due to its:

• large mass.

• many moons.

• rapid rotation.

• ring system.

• strong magnetic field.

Our most detailed knowledge of Uranus and Neptune comes from:

• ground-based radio telescopes.

• manned missions.

• spacecraft exploration.

• the Hubble Space Telescope.

• ground-based visual telescopes.

A day at the north pole of Uranus lasts:

• about 21 years.

• about 7 hours.

• about 84 years.

• about 8 hours.

• about 42 years.

Neptune and Uranus have a bluish tint because:

• their atmospheres contain methane, which absorbs red light.

• at their distances, the Sun appears blue, the red absorbed by dust in the ecliptic.

• their atmospheres contain hydrogen and helium.

• ammonia ice reflects blue light better than any other color.

• they are far away and distance makes objects appear bluish.
