Trans-Neptunian objects (TNOs) with diameter greater than 100 km currently moving in not too eccentric orbits could be formed directly by the contraction of large rarefied condensations. Along with the gravitational influence of planets, gravitational interactions of TNOs played a certain role in their orbital evolution as well. More than 20% of Earth-crossing objects could have come from the trans-Neptunian belt. TNOs and Centaurs (invisible comets mainly beyond Jupiter) could produce an important contribution to the dust content of the interplanetary dust cloud.
