Question 1

The largest gap in the rings of Saturn is called ______.
A) Cassini's division
B) Cap A
C) Encke's division
D) spiral division

Accepted Answer

Cassini's Division is the most prominent gap in the rings of Saturn, discovered by Giovanni Domenico Cassini in the 17th century. It separates the A and B rings.

Question 2

These hold the rings together by their gravitational forces:
A) gravity moons
B) irregular moons
C) ring moon
D) shepherding moons

Accepted Answer

Shepherding moons are responsible for holding the rings together through their gravitational forces. They orbit near the edges of rings and their gravity helps to maintain the shape and sharp edges of the rings, preventing the particles from spreading out.

Question 3

The Roche limit is about ____ the planet's radii.
A) 1.44
B) 2.44
C) 3.44
D) 4.44

Accepted Answer

The Roche limit is approximately 2.44 times the radius of the planet. This is a theoretical limit within which a celestial body, held together only by its own gravity, will disintegrate due to the planet's tidal forces exceeding the body's cohesive forces.

Question 4

This satellite is unusual in that one hemisphere is nearly black, and the other is white.
A) Amalthea
B) Hyperion
C) Iaepetus
D) Io

Accepted Answer

Iapetus, a moon of Saturn, is notable for its striking two-tone coloration, with one hemisphere being significantly darker than the other.

Question 5

Miranda's complex pattern may have been caused from ______________.

Accepted Answer

The answer of Miranda's complex pattern may have been caused...

Question 6

Long cracks called ____ have been discovered on some moons.

Accepted Answer

The answer of Long cracks called ____ have been discovered...

Question 7

Most moons in the solar system that are large are in regular orbits.

Accepted Answer

Most large moons in the solar system are in regular orbits, meaning they have low inclinations and eccentricities, and orbit their planets in the same direction the planets rotate. This is a result of their formation processes, typically believed to have formed from the circumplanetary disks of material that surrounded the planets in the early stages of the solar system's evolution.

Question 8

Miranda is a strange surfaced moon around Neptune.

Accepted Answer

Miranda is one of Uranus's moons, known for its highly varied and unique surface features.
