Rings, Moons, & Pluto

The composition of Saturn's ring particles is predominantly water ice.

Saturn's rings exist because they lie within the planet's Roche limit.

Two small shepherd satellites are responsible for the unusually complex form of Saturn's F ring

Titan's surface is obscured by thick clouds of ammonia ice

Triton's orbit is unusual because it is retrograde

The atmospheric pressure at the surface of Titan is

Which of the Galilean moons is the densest and most geologically active?

Pluto's density is most similar to

Pluto was discovered in

The two names most associated with the discovery of Pluto are

Charon's orbit

Pluto is most similar to

What is so unusual about Pluto's orbit?

Triton and Pluto both probably originated in the Kuiper Belt

Pluto is smaller than many moons in the solar system.

Pluto's classification as a planet has been called into question

Pluto is visible to the naked eye on extremely dark nights

is probably one of the largest of the Kuiper Belt bodies beyond Neptune

What is thought to be the cause of Io's volcanoes?

Which are the four Galilean moons of Jupiter?

In size and density, both Io and Europa resemble

The mare on Ganymede were formed by

Of the Jovian satellites, which shows the oldest, most cratered surface?

The largest moon in the solar system, bigger but not as massive as Mercury, is

Which of these moons has the densest atmosphere?

At Titan, the oceans are made of liquid

The atmosphere of Titan is composed mostly of

What is true of Titan's atmosphere?

The erupting geysers of nitrogen gas on Triton

Which statement about Jupiter's rings is true?

Inside the Roche Limit

The surface of Io looks most like the pack ice of the Arctic Ocean of Earth.

Io's internal heat is due to tidal interactions with Jupiter and Europa

Of all the Galilean satellites, the surface of Europa is the youngest in age.

Ganymede is the largest satellite in the solar system.

Titan's surface has been mapped using Earth based visual telescopes

Methane drives the weather of Titan, for there it can be liquid, solid, or gas

Like Titan, Triton has a nitrogen atmosphere

Alone among all the large moons, Triton orbits Neptune retrograde, and also at a 20 degree inclination to Neptune's equator

Probably the next satellite to get turned into ring debris will be Neptune's backward moon, Triton

Saturn's rings are composed of __________.

Saturn's rings look bright because __________.

The largest moon in the solar system is

The jovian moon with the most geologically active surface

Strong evidence from both surface features and magnetic field data support the existence of a subsurface ocean on

What is responsible for the volcanic activity on lo?

The most distant of Jupiter's moons

The fact that Europa orbits Jupiter twice for every one orbit of Ganymede is an example of
