14. Formation of the Solar System The stages of solar system formation start with a protostar embedded in a gas cloud, then to an early star with a circumstellar disk, to a star surrounded by small "planetesimals" that are starting to clump together to a solar system like ours today.

16. Composition of the Solar System Jovian planets: Jupiter, Saturn, Uranus, Neptune –Large masses & low densities. –Mainly composed of gaseous H & He and frozen C-H-N volatiles. –Interiors may be similar to that of Earth

17. Composition of the Solar System The inner, terrestrial planets: Small masses & high densities. –Mercury: No atmosphere. Similar in composition to Earth. –Venus: Dense atmosphere of CO 2 & N. Similar in composition to Earth. –Earth: More about “us” later. –Mars: Polar ice caps in winter – water? Uniform chemical composition – i.e. no iron core and silicate mantle as in Earth.

18. The Asteroids www.aerospaceweb.org/

20. Composition of the Solar System The asteroids: Located in a belt between the terrestrial and Jovian planets. Meteorites: Most are probably fragments from the asteroid belt of our solar system. –Siderites, or “irons” (98% metal) –Siderolites, or “stony irons” (50% metal, 50% silicate) –Aerolite, or “stones” (silicate > metal)
