Document Summary
4 features of our solar system: exhibits clear patterns of motion (counter clockwise) All the planets orbit the sun in nearly the same plane and in the same direction. Also, the same as the sun"s rotation and most planets" rotations. Terrestrial planets made entirely of metal and rock, high density and their. Jovian planets largely made of materials that are usually gaseous under earthly atmospheres are minor constituents of the planet"s mass: there are two types of planets jovian and terrestrial conditions. Materials such as hydrogen, helium and hydrogen compounds. The pressure is so high that the gasses are compressed into liquid or high- density forms. Jovian planets contain many moons which contain a substantial amount of water in addition to rock and metal. All 4 jovian planets surrounded by massive rings: asteroids and comets. Asteroids chunks of rock and metal that orbit the sun but are much smaller than planets.
