Abstract	It is accepted that the orbital distribution of long-period comets coming from the Oort cloud is isotropic. That leads to the isotropic and spherical structure of the Oort cloud. However, the formation theory of the Oort cloud from the protoplanetary disk indicates the non-isotropic distribution of the long-period comets. We process the “Catalogue of Cometary Orbits 2005” so that we can compare the observation to the theory and reproduce the Oort cloud structure.
Keywords	Oort cloud, long-period comets, the Galactic tide, stellar encounters
