THE ORIGIN OF THE SOLAR SYSTEM

• - suggested by ptolemy / aristotle

• - states that the eartyh is at the center of the social system

  • - earth centered model

• - suggested by nicolas copernicus

• - states that the earth and planets revolve around the sun

• - sun centered solar system

states that the stars appear to be moving because of what type of earth' s motion

descartes vortex theory

• rene descartes; states that pre-solar materials move in a whirpool like motion

• george louis leclerc comte de buffon; states that the solar system was formed due to a collision between a sun and giant coment, creating a giant debris

• james hopwood jeans and harold jeffreys; states that the sun encountered a rougue star and hot gas was removed from both stars; less dense material -> outer planets, denser material -> inner planets

• immanuel kant -> modified by pierre simon laplace; states that a slowly rotating great cloud of gas and dust (nebula) collapsed and flattened like a pancake

buffon's collision theory

• immanuel kant -> modified by pierre simon laplace; states that a slowly rotating great cloud of gas and dust (nebula) collapsed and flattened like a pancake

• james hopwood jeans and harold jeffreys; states that the sun encountered a rougue star and hot gas was removed from both stars; less dense material -> outer planets, denser material -> inner planets

• suggested by george louis leclerc comte de buffon; states that the solar system was formed due to a collision between a sun and giant coment, creating a giant debris

• victor safronov; states that plantes came from a solar nebula and flattened into a disk shape

tidal theory

• victor safronov; states that plantes came from a solar nebula and flattened into a disk shape

planets and other materials that revolve in the same direction

buffon's collision theory objection/s

• comets are far too small to have created the solar system in this way

• when comments and the sun collides, it will usually be too hot and the comet just ends up melting

• close encounters between stars would not occur often

• the sun should be spinning more rapidly; planets should be rotating far too slower
