Starting distribution

   


Distribution at t=4 GY

   

Evolution of the total mass of the Oort cloud (Earth mass)

   

Evolution of the mass of the Oort cloud for R > 100 m ( Earth mass)

   


Evolution of the mass of the Oort cloud for R > 1 km ( Earth mass)

   

Ratio of final distribution to the initial one : bodies < 1 km disapear preferentially
