Transneptunian families of comets

Abstract

The distribution of aphelions cometary orbits in order of distance from the Sun for interval of 15–200 A.U. is investigated. We've discovered that the frequency of aphelions cometary orbits decreases at the distance greater than 120 A.U. The resulting distribution points out the existence of three transneptunian families of comets at medium distances of 56, 86, and 106 A.U. It is suggested that the existence of hypothetical planets Transneptune-1, Transneptune-2, Transneptune-3 gives rise to these families of comets.
