giant planets

The planets Jupiter, Saturn, Uranus, and Neptune, which have diameters between 3.9 and 11.2 times that of the Earth and masses of between 14 and 318 Earth masses. They orbit the Sun at mean distances ranging from 5.21 AU for Jupiter to 30.06 AU for Neptune in periods from 11.86 to 164.79 years. All have low densities – from 0.7 to 1.8 times that of water – and are probably composed largely of hydrogen in its molecular or metallic state. Their visible surfaces are thought to be clouds of ammonia or methane. They all have planetary ring systems and share at least 150 satellites between them (see Table 2, backmatter).

described a new indivisible geoscience paradigm that begins with and is the consequence of our planet's early formation as a Jupiter-like gas giant and which permits deduction of: (1) Earth's internal composition and highly-reduced oxidation state; (2) Powerful new internal energy sources, protoplanetary energy of compression and georeactor nuclear fission energy; (3) Georeactor geomagnetic field generation; and, (4) Decompression-driven geodynamics that accounts for the myriad of observations attributed to plate tectonics without requiring mantle convection.
