Assume That We Discover a New Moon of Jupiter

Multiple Choice

Assume that we discover a new moon of Jupiter. It orbits Jupiter at a large distance and in the opposite direction that Jupiter rotates. It is much smaller than most of Jupiter's other moons and has a density close to that of Earth rocks. Therefore, this moon is most likely:

A) a regular moon that formed with Jupiter in the early solar system
B) an irregular moon that is most likely a captured asteroid
C) an irregular moon that is most likely a captured comet
D) an irregular moon that is most likely a protoplanet which collided with Jupiter in the early solar system and then was caught in orbit by Jupiter's gravity
E) more information is needed before any conclusion can be made
