THE OUT OF ECLIPTIC DISTRIBUTION OF INTERPLANETARY DUST AND ITS RELATION TO OTHER BODIES IN THE SOLAR-SYSTEM

We discuss the out-of-ecliptic component of the interplanetary dust cl oud and its relation to the other small bodies in the solar system. Th e determination of the mass loss of comets, so far is quite uncertain and doesn't allow a finite study of the mass input to the dust cloud. However it is shown, that the dust particles in the inner solar system , i.e. within the earth orbit are most probable produced from a collis ional evolution of larger, meteoroid, fragments of cometary origin. A further component of interstellar dust is especially important in the outer solar system and perhaps for the collisional evolution of the sm all bodies.
