How does the solar system work?

At a distance of about 40 AU from the Sun is the boundary of the planetary system, the mass of which is close to 450 Earth masses. Zone from 40 au up to 2000 AU represents a gap in the distribution of matter. Further, up to a distance of 20,000 AU. an internal cometary cloud is concentrated, the mass of which can be 20 times the mass of the planets. And finally, up to a distance of 50 * 10 ^ 3 AU. the cometary halo extends. The halo mass is about 1/4 the mass of all planets.
