From a review of the methods that have been used so far, we estimate the present massthe scattered disk to be in the range 0.01 to 0.1 M . We review the dynamics of the scattereddisk, paying special attention to the mean-motion and Kozai resonances. We discuss the originof the scattered objects both as coming from the Kuiper belt and as remnants of the scatteringprocess during Neptunes migration. We stress the importance of the mean-motion resonancecoupled with the Kozai resonance in raising the perihelia of scattered disk objects, emphasizingthat fossil and live high perihelion objects could thus have been produced. We analyze othermechanisms that could have implanted the detached scattered objects onto their current orbits,focusing on a few that demand specific explanations. We explore the different end statesscattered disk objects and highlight the importance of their transfer to the Oort cloud.
