System Generations

Based on current theory:

(I) First Generation system is composed almost entirely of hydrogen gas: suns and gas giants.

(II) Second Generation is built off of the debris from a Generation I supernova; it has elements up to Iron (atomic number 26) or partial 4th Period elements.

(III) Third Generation is built off of the debris from a Generation II supernova that has elements up to Tellurium (atomic number 52) or most of the 5th Period elements.

(IV) Fourth Generation is built off of the debris from a Generation III supernova that has elements up to Rutherfordium (atomic number 104) or the elements transuranium elements.

By this methodology, the Earth system is a Generation IV system built off of the remnants of three prior supernovas.
