Abstract

Theoretical Formulation of the Origin of Cataclysmic Late Heavy Bombardment Era based on the New Perspective of Birth and Evolution of Solar Systems

Bijay Kumar Sharma*

A Late Heavy Bombarment (LHB) era occurred from 4 Gya to 3.8 Gya characterized by a cataclysmic spike in cratering events on our Moon as analyzed by Moon’s Apollo mission. It is hypothesized that this spike occurred due to Mean Motion Resonance (MMR) 1:2 of Jupiter and Saturn. The Solar System was precipitated from the Solar Nebula at 4.567 Gya. In 7 My Jupiter was born that is at 4.56 Gya. In 30 My gas giants and ice giants were formed at 4.537 Gya and in 100 My terrestrial planets (Earth, Mars, Venus and Mercury) formations were completed. Based on the new perspective of the birth of planets and exo-planets it is postulated that Jupiter and Saturn born at first Clarke’s orbits fall into super-synchronous orbits and are launched on expanding spiral orbit. If Saturn is born 25 My later than Jupiter, MMR 1:2 crossing occurs 300 My later than the birth of Jupiter. This MMR crossing acts as a stimulus and Neptune is launched on an outward spiral path towards Oort’s Cloud resulting in a heavy shower of comets and asteroids from Oort’s Cloud to the inner part of solar system resulting in a catacalysmic spike in cratering rate during Late Heavy Bombardment Era (LHB Era) from 4 Gya to 3.8 Gya. Clearly there is 500 My delay from the birth of Jupiter to the LHB era whereas MMR 1:2 crossing of Jupiter Saturn occurs 300 My from the birth of Jupiter. This extra 200 My delay occurs due to delayed response of Neptune. This point needs to be examined through further research.
