This paper describes two computer experiments carried out with a CDC-Cyber 74 program for computer simulation of a large number of objects in orbit about a central body or primary. The first experiment was started with 125 planets of which the two largest ones had coplanar orbits and masses comparable to those of Jupiter and Saturn, respectively. Their semi-major axes and eccentricities were, however, much larger. The smaller planets had a distribution promoting the formation of an axial meeting area. The experiment gives information relevant to the focusings of planetary orbits into a common plane and to the formation and stability of an axial meeting area. Together with the next experiment, it gives information on the development of commensurabilities (or resonances) with the largest planets. The second experiment started with 55 planets with a mass not greater than about 20% of Jupiter's, but several with orbits close to a common plane. The aim of the experiment was to investigate whether successive captures followed by planetary fusion could lead to the formation of major planets comparable to Jupiter and Saturn, and in similar orbits. This experiment also gives information relevant to the commensurability problem.
