The explosive reactions and forces, from gravity to nuclear fsion, which formed our Solar System.
- Our Solar System is the region of space which falls within the gravitational influence of our Sun.

- The Sun took 10 million years to form.
- Metal and dust particles clustered to form rocks, which eventually formed planets in a process known as accretion.
