The Solar System

Refers to the Sun itself and every celestial object that revolves around it.There are 8 planets and their natural satellitesDwarf planetsAsteroidsCometsMeteors, Meteorites, Meteoroids

THE SOLAR SYSTEM

Universal Law of Gravitation

Sir Isaac Newton explains what keeps the celestial objects, particularly the planets, in orbit around the sun.

Gravitational Pull or the force of attraction exerted by the

pulling them towards it, is one of the forces that hold the planets in orbit.

Force of Inertia or the force exerted that keeps the planets moving and spinning.

Gravity and Inertia work together resulting to a stable planetary orbit.

How the Solar

System Evolved

Theories to explain the beginning of the Solar System

Planetisimal TheoryProposed by Georges Comte de Buffon (French

Scientist) in 1778.This theory states that the solar system was

formed when the sun collided with another star.Causing the large masses of materials from the two

stars to be thrown off into spaceThen, the said materials cooled and condensed then

formed small bodies, which we now call, planets.

Planetisimal Theory Georges Comte de Buffon

Companion Star Theory

According to a British Astronomer, Fred Hoyle that the sun once had a companion star.

The said companion star exploded when it collided with the sun.

Then, the materials from the explosion were held by the sun’s gravitation.From these materials, various planets and other

objects in the solar system were formed.

Companion Star Theory Fred Hoyle

Proposed by Marquis De Laplace, a French Astronomer in 1976According to him, a vast, saucer-shaped nebula (similar to a

protostar) was swirling slowly in space.And, suddenly, it cooled and shrank

Causing it to spin faster in space.Due to the speed of its spin, the rings of materials broke away

from its outer edge.Those rings gave rise to planets, and when the center of the

nebula condensed, it then became the Sun.
