Which of the following spacecraft is the only one to have flown past Neptune?

Voyager 2

Which of the following spacecraft is the only one to have flown past Uranus?

Voyager 2

The Cassini-Huygens spacecraft

Went into orbit around the planet Saturn and Went into orbit around the planet Saturn and dropped a probe into Titan's atmosphere.

Saturn's magnetic North and South poles are

almost exactly aligned with its rotation axis.

The rotation axis of Uranus is

almost in the plane of its orbit so that its ring system can sometimes be seen as near-circles.

Titan has

an atmosphere whose temperature and pressure permit liquid methane.

Saturn has

an extensive ring system made of ice-covered rocks.

What we refer to as a `Saturn Ring-plane Crossing' corresponds to what season on Saturn?

fall or spring equinox

The moon Miranda is peculiar because it

has a surface feature that looks like a giant check mark.

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 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.

The magnetic field of Jupiter is

tilted relative to the planet's rotation axis but not offset from its center.

Saturn is about

twice as far from the Sun as Jupiter
