How do they form?
Theories of Formation
• Accretion
- Creation is like that of planets
• Capture
- Some debris in space collided or got caught by larger
planets.
• Fission
- Matter thrown off a planet enters orbit around the
planet
• Impact
-Big body hits planet hard enough to eject matter, which
cools and condenses into a moon.
