Origins and Structures of the Solar System

By: Jedd Paltao

ORIGIN OF THE SOLAR SYSTEM

The solar system was formed around 4.5 billion years ago from a giant swirling clouds of dust.

The Nebular hypothesisDeveloped by by Immanuel Kant and given scientific form by P. S. Laplace at the end of the 18th century

A. solar nebula

B. contraction into rotating disk

C. Cooling causing condensing into tiny (dust sized) solid particles

D. Collisions between these form larger bodies

E. These accrete to form planets

Protoplanet hypothesis by: Carl von Weizsacker and Gerard Kuiper.

(A)The solar system begins to form as a rotating cloud, or nebulae, collapses.

(B) Instabilities in the nebulae cause dust particles to stick together.

(C) The Sun begins to radiate energy and vaporize dust in the inner part of the Solar System.

Structure of the Solar System

The solar system has three distinct regions

Outer region / Jovian beyond asteroid belt and are large gaseous, low density worldsJupiter, Saturn, Uranus, Neptune and Moons

Trans-Neptunian regionKuiper Belt and Oort Cloud

Inner Region / Terrestrial planets are small, dense, rocky worldsMercury, Venus, Earth, Mars, Asteroids

Solar System is still filled with smaller bodies, such as satellites , asteroids, and comets

Inner Region / Terrestrial planets

Solar System Formation1 Inner solar system -- volatiles boil off, and creates small terrestrial planets

2 Outer solar system -- large planet cores form rapidly from refractory and icy material, acquire large gas envelopes ( Jovian Planets)

3 Edge of solar system -- leftover and ejected icy planetesimals form Kuiper belt and Oort cloud
