theory
1.Nebular Hypothesis
-
spinning cloud of dust made of mostly light elements,called nebula,flattened to a protoplanetary disk and became a solar system consisting of star with orbiting planets
Protoplanet Theory
the whirling cloud of gas or dust becomes a planet by condensation during the formation of Solar System
This idea has replaced the original nebular hypothesis of Kant and Laplace as well as the later planetesimal hypothesis
Planetismal Theory
when a planetary system is forming, there is a protoplanetary disk with materials from nebulae, and it will be gradually pulled together by gravity to form small chunks
