Exam 11: The Giant Planets

The synchrotron radiation (radio waves) that astronomers first observed from Jupiter in the 1950's comes from:

Which of the jovian planets has the shortest period of rotation (the shortest day)?

The largest planet in the solar system (by mass) is

What do the magnetic fields of Jupiter, Uranus, and Neptune have in common?

Which of the following does the composition of a planet like Jupiter resemble:

The planet that orbits "on its side" (i.e. has its rotation axis perpendicular to the plane of its orbit) is:

What allowed the Voyager 2 spacecraft to make a "tour" of all four of the jovian planets in the late 1970's and the 1980's?

The same process that explains why astronomers see less helium in the upper atmosphere of Saturn when they take spectra also explains

At their centers, all the jovian planets have cores made of:

Which of the following is NOT a correct statement about the ways the jovian planets differ from the terrestrial planets?

Which of the following is NOT a way that Jupiter differs from terrestrial planets?

Which of the following characteristics distinguishes Uranus from every other planet in our solar system?

Which of the following statements about the seasons on Jupiter is correct?

Much of what we have learned about the jovian planets and their satellites has come from the work of two spacecraft called:

Astronomers believe that Jupiter's strong magnetic field is caused by

At the moment when the Voyager spacecraft got closest to Uranus, the Sun was shining directly on the planet's south pole. Uranus takes about 17 hours to rotate once on its axis. If Voyager took a photo of the south pole 8.5 hours later, what would it observe?

The element that can act like a metal when it is under tremendous pressure and is probably responsible for Jupiter and Saturn's magnetism is:

Which of the following statements about Jupiter's magnetosphere is TRUE?

By far the most abundant element in the giant (jovian) planets is:

In the far future, a daring interplanetary tourist wants to go "hang-gliding" on the jovian planet with the highest equatorial wind speeds. Which planet would have the fastest wind at its equator?
