1 “THE SOLAR NEBULAR THEORY”

2  A huge nebula condenses under its own weight due to gravitational attraction.

3 contracting, rotating, spinning and begins to flatten into a disk  The nebula is contracting, rotating, spinning and begins to flatten into a disk.

4  The sun forms in the center and rocky material collides, forming bigger and bigger clumps that become the planets. This process of clumping together is called accretion.

5  The sun contracts, and begins to shine. Nuclear fusion has taken place. Intense solar radiation called the “ T- Tauri Wind ” blows away un-accreted gas and dust, clearing away extra debris from the planets. This reduces impact collisions!

6  The Sun begins to burn hydrogen and the planets complete their formation. Our solar system is made up of one star, 8 planets, an asteroid belt, 166 moons, several dwarf planets, comets and icy, rocky bodies in the Kuiper Belt at the outermost region of our system.
