As saturn rotates,
both its magnetic poles remain almost motionless t its geographic poles
Which of the following temperatures is closest to what you might expect on the planet Jupiter?
-250F
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 moon 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 a planet's rotation axis is defined so that a planet that is rotating in the usual direction about an axis that is perpendicular to the plane of the solar system would have an inclination of 0°, while a planet that is rotating in the opposite (retrograde) direction about an axis that is perpendicular to the plane of the solar system would have an inclination angle of 180°. The inclination angle of the planet Uranus is closest to
98 degrees
Which of the following objects is the largest moon of Jupiter?
Ganymede
Which of the following spacecraft were the first to fly past Jupiter?
Pioneer 10 and Pioneer 11
With of the following spacecraft was the first to fly past Saturn?
Pioneer 11
The Cassini- Huygens spacecraft
Went into orbit around the planet 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
Saturn has
an extensive ring system made of ice-covered rocks
Neptune's magnetic North and South poles are
displaced from its rotation axis poled 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
the rotation rate of Saturn
has not been exactly determined because different methods give somewhat different results
the rotation axis of Neptune is
inclined at an angle to the perpendicular that is similar to Earth's rotation axis
the rotation axis of Saturn
inclined at an angle to the perpendicular that is similar to Earth's rotation axis
The blue color of the planet Uranus is caused by the presence in its atmosphere of
methane
the magnetic field of Saturn is
similar in intensity to the Earth's magnetic field
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
