Description

We present N-body simulations of the Solar System incorporating non-gravitational forces (NGFs) generated by volatile sublimation in comets, using the REBOUND code. Our study focuses on quantifying how these jet forces influence comet dynamics and their role in delivering water to early Earth. By tracking close approaches within Earth's Hill sphere, we evaluate how NGFs modified the impact flux of water-rich comets throughout Solar System history. These simulations provide critical constraints on whether outgassing effects significantly enhanced aqueous delivery to primordial Earth compared to purely gravitational models, shedding light on the cometary origin of terrestrial oceans
