These are the nebular hypothesis of laplace, the planetesimal hypothesis of chamberlin and moulton, and the capture theory of see darwings theory of tidal friction is scarcely a distinct hypothesis, but is mentioned separately on account of its application to all of the others the main features of these hypotheses will be. The tidal or gaseous hypothesis this hypothesis, like the planetesimal hypothesis which preceded it, also involves an original sun that had a close encounter with a passing star known also as the tidal disruption or tidal filament hypothesis, this conception of how our solar system formed was proposed in 1918 by two. This is a type of dynamic encounter theory which believes that material is pulled out of the sun by an external force such as gravitational pull resulting from the dynamic encounter of the sun with another star chamberlin and moulton ( 1904), two american scientists, put forward this hypothesis according. The chamberlin–moulton planetesimal hypothesis was proposed in 1905 by geologist thomas chrowder chamberlin and astronomer forest ray moulton to describe the formation of the solar system it was proposed as a replacement for the laplacian version of the nebular hypothesis that had prevailed since the 19th.

Planetesimal hypothesis • we now think of a “three-stage” model for planet formation: 1) dust (~um) → planetesimals (~km) sticking due to contact forces during collisions 2) planetesimals (~km) → proto-planets / cores (~1000km) gravity (between solids) 3) proto-planets / cores → planets gravity (gas accretion ) and giant.
