Most people are unaware that traditional models do not explain chemical composition of the solar system fully. The presence of such elements as certain p-nuclei or post-post-Fe-nuclei, remains not yet understood. We propose a mechanism which can explain appearance of all non-native elements in the solar system. The hypothesis involves an explosive “collision” of a traveling from afar giant-nuclear-drop-like object (with specific equation of state of its matter) within the inner part of the solar system. The “nuclear fog” and debris, through the multitude of reaction channels (capture and fission) and nuclei transformations, enriched the solar system and led to the eventual formation of the terrestrial planets that pre-collision did not exist. This offers a possible explanation for the planets’ inner position and compositional differences within the predominantly hydrogen-helium rest of the solar system.
