Solar system begins 4567.3 mya

A shock wave from nearby supernova caused the molecular cloud to collapse and the initiation of the solar nebular representing the beginning of our solar system. Gravitational interactions cause the material within the cloud to spin and flatten out to form a protoplanetary disk. First minerals that condense from the cloud are now found as calcium-aluminium-rich inclusion in carbonaceous chondrite meteorites.
