What is the Great Red Spot?

100

This is why Saturn would float

It is the most dense planet

100

This gas gives Uranus its pale blue-green color due to its absorption of red light.

What is methane?

100

Neptune was the first planet discovered through this method rather than direct observation.

What is mathematical prediction (or perturbations in Uranus's orbit)?

100

This Galilean moon of Jupiter is believed to have a subsurface ocean beneath its icy crust, making it a candidate for extraterrestrial life.

What is Europa?

200

How many rings does Jupiter have?

4

200

These complex, icy structures orbit Saturn and are divided into sections named with letters in the order they were discovered.

What are Saturn’s rings?

200

Unlike other planets, Uranus has this unusual property

What is it rotates on its side (or extreme axial tilt of 98 degrees)?


200

The strongest what, is found on this planet?

Winds

200

This largest moon of Saturn has a thick atmosphere and surface lakes of liquid methane and ethane.

What is Titan?

300

Since Jupiter has the faster rotation, it also has what type of day?

Shortest

300

Saturn’s  equatorial bulge is primarily caused by this planetary characteristic.

What is its rapid rotation?

300

The outer atmosphere of Uranus lacks this prominent feature seen in Jupiter and Neptune, making it appear relatively bland.

What are large visible storm systems (or atmospheric bands)?

300

This large storm system, first seen by Voyager 2, was Neptune’s version of Jupiter’s Great Red Spot.

What is the Great Dark Spot?

300

This is the largest moon of Saturn

Titan

400

Jupiter has this strongest type of field

Magnetic

400

Saturn’s rings are thought to be relatively young and may have formed from this type of catastrophic event.

What is the breakup of a comet or moon (tidal disruption event)?

400

This spacecraft, which flew by Uranus in 1986, remains the only one to have visited the planet.

What is Voyager 2?

400

Despite being farther from the Sun than Uranus, Neptune has stronger winds due to this internal characteristic.

What is a significant internal heat source (or residual heat)?

400

This is the largest moon of Uranus

Titania

500

This is the largest moon in the Solar System

Ganymede 

500

What shape is the storm at the top of Saturn?

Hexagon

500

What other type of Giant is Uranus called?

ICE

500

What is responsible for Neptune's blue color?

The methane absorbs the red light

500

This moon of Neptune is believed to be a captured Kuiper Belt object and has retrograde orbit.

What is Triton?
