PRESENTATION OUTLINE
Collapse Of The Solar Nebula
About 4.6 million years ago, the solar nebula collapsed due to an undetermined outside force.
Formation Of The Sun
In a wide expanse of space, gravity drew dust and gas together to create the young solar system. The sun formed first from the vast material.
Formation Of The Planetesimals
As the sun was forming dust grains collided and stuck together and grew, which eventually created planetesimals.
Formation Of The Planets
As the planetesimals collected more dust and grew more, they evolved into planets.
