What are natural satellites and how did they form? By: Zoren Valmonte Grace Sung

What are natural satellites? • A natural satellite, or moon, is a celestial body that orbits another body which is called its primary.

How did they form? Different types of are thought to come from different origins.

Accretion theory

Capture theory

Other theories • Fission: Matter is thrown off a body that is spinning very fast. This matter then enters orbit around the parent planet • Impact: A big enough body hits the parent hard enough for matter to be ejected into space. This matter enters orbit around the parent planet and cools and condenses, forming a moon.

Types of Natural Satellites Regular Satellite Irregular Satellite

Regular Satellite • Regular satellites are natural satellites which: Orbit relatively close to their primary/parent body • Have a prograde orbit • Orbit in the same plane or near enough as their primary; • Have a near-circular orbit. .

Irregular Satellite • Irregular satellites are natural satellites which exhibit one or more of the following Orbit distantly from their parent body: • Have a retrograde orbit • Orbit in a plane which is significantly inclined compared to that of their parent body's; • Have a highly eccentric (noticeably elliptical) orbit. .
