Quiz Answer Key and Fun Facts

1. This moon contains Loki, the most powerful volcano in the solar system.

Answer: Io

Io is the most volcanically active object in our solar system; it contains at least 100 active volcanoes.

2. Which Galilean moon was the last to be discovered?

Answer: Ganymede

Io, Callisto, and Europa were discovered on January 7, 1610. Ganymede was discovered 3 days later. When Jupiter was first viewed by Galileo, Ganymede was behind Jupiter.

3. This Galilean moon contains Gipul Catena, a series of impact craters stretching across in a straight line.

Answer: Callisto

Gipul Catena was probably caused by an object that was tidally disrupted as it passed close to Jupiter, and impacted on Callisto in along its path.

4. Containing both rough & cratered surface, this moon seems to have a history of tectonic movement!

Answer: Ganymede

Its terrain is both old and new.

5. The brightest of the Galilean moons, this place may have water ice, and possibly extraterrestrial life.

Answer: Europa

It contains cracked and crumpled ice, much like the ice in the Arctic Ocean on Earth.

6. Which Galilean moon is yellow and red?

Answer: Io

Io's many volcanoes give off large amounts of sulfur compounds, which sparkle the surface yellow and red.

7. This is the only moon in our solar system to have a global magnetosphere.

Answer: Ganymede

A magnetosphere is the region around an astronomical object which is covered by a magnetic field. Only Earth, Jupiter, Saturn, Neptune, Uranus, Mars, and Ganymede have magnetospheres. Mars and Ganymede have magnetospheres, but are too weak to trap plasma.

8. How many of the Galilean moons can you see with a small telescope?

Answer: 4

You can see all four of the Galilean Moons through just about any telescope, even with binoculars.

9. List the Galilean moons from largest to smallest in size.

Answer: Ganymede, Callisto, Io, Europa

Ganymede is the largest moon the our solar system, it's even bigger than Mercury.

10. List the Galilean Moons in their order from Jupiter.

Answer: Io, Europa, Ganymede, Callisto

Io, Europa, Ganymede, and Callisto; each different in their own ways! Io looks like a pizza, Europa has cracked ice, Ganymede is huge, and Callisto is sparkling with rays across its dark surface.
