Astronomy Exam 3
As Saturn rotates,
both its magnetic poles remain almost motionless at its geographic poles
Which of the following temperatures is closest to what you might expect on the planet Jupiter
-250
As of 2018, how many space probes had flown past Uranus closely enough to take detailed pictures?
1
As of 2018, how many space probes have flown past Neptune closely enough to take detailed pictures?
1
How many of the moons of Saturn are larger than the Earth's Moon?
1
Uranus rotates on its axis once in about
17 hours
Compared to the Earth, the planet Uranus is roughly
4 times as large
The inclination angle of the planet Uranus is closest to
98
The Galilean satellites of Jupiter are
Callisto, Europa, Ganymede, and lo
Which of these planets has a rotation axis that is inclined in much the same way as that of Earth?
Neptune
Which of the following spacecraft were the first to fly past Jupiter?
Pioneer 10 and Pioneer 11
Pioneer 11 was an early space probe sent to fly past
Saturn
Which of the following objects has a magnetic field similar in intensity to the Earth's field?
Saturn
Which of the following planets has a system of rings made of ice-covered rocks ?
Saturn
Jupiter has
a few rings made of dark rocks
The magnetic field of Jupiter indicates that its core must contain large amounts of
a liquid that can conduct electricity
Jupiter has
an atmosphere of Hydrogen and Helium with no real surface
Neptune has
an atmosphere of Hydrogen and Helium with some methane
Neptune's magnetic North and South poles are
displaced from its rotation axis poles and also from the center of the planet
Uranus's magnetic North and South poles are
displaced from its rotation axis poles and also from the center of the planet
As Saturn orbits the sun, we see its rings from different angles. We see the rings
edge-on as a straight line exactly twice each orbit
The rotation rate of Saturn
has not been exactly determined because different methods give somewhat different results
The blue color of the planet Uranus is caused by the presence in its atmosphere of
methane
Jupiter has the most mass of any planet in our Solar System and is also the largest planet. Objects that have still more mass than Jupiter and are not stars are usually
smaller than Jupiter
The magnetic field of Jupiter is
tilted relative to the planet's rotation axis but not offset from its center
The Cassini-Huygens spacecraft
went into orbit around the planet Saturn
