Proper motion (mas/yr) = +4.65 +81.96 comets as Earth was for the first billion years of existence. We have numerically investigated the dynamics of how a close stellar fly-by encounter of a symmetrical circumstellar planetesimal disc can give rise to the many kinds of asymmetries and substructures attributed to the dusty disc of Beta Pic.
