Document Summary
Creating a galaxy and creating a solar system are similar. The disk of mass is rotating; the gravity pulls the mass to- The rings wards the center, which forms a sun or a black hole. spinning around the sun will become the planets. The larger particles are dragging in the smaller ones, which makes them even bigger. The composition in each each ring will be different. The ring is colder on the outside, hotter on the inside. That makes certain gases con- dense at different distances. Olivine and iron condense around 1800 celcius which forms metallic iron and olivine. The snowball goes around and gathers more dust, making planet earth. Going further out, the tempera- ture drops lower, making water vapour condense into liquid and ice. Carbon dioxide become solid at -56 celsius and is dry ice. Ammonia is also a composition of the gas planets.
