Based on recent developments in astronomy, pertaining to a greater degree of measurement, the mass of the Oort cloud around Sol is apparently only about 1.5 times the mass of earth,in contrast to over a thousand times, roughly, as previous thought, which got me wondering, if there might be a scenario where an Oort cloud would have substantial mass, and moreover, would consist of planets full on planets rather than our's which consits of a handful of planetoids and a whole lot of comets.

I know the field(of astronomy) is currently evolving, and there's a great deal of unknown aspects regarding the formation of solar systems but one idea I do have is, planetoids drifting through an outer system and being captured upon the stars initial formation, with an outer system with a rather high density of interstellar gas, and so encouraging the formation of said planets.

  • $\begingroup$ The gravitational interactions that kick some planetesimals out to very large distances, populating the Oort Cloud, shift the orbits of planets by very tiny amounts. So you simply can't produce an Oort Cloud of "full on planets". $\endgroup$ Apr 9 at 19:30
  • $\begingroup$ At the distance of the Oort cloud the sun's gravity is so weak, that if you'd put a cloud of Jovians there, their mutual scattering perturbations would quickly depopulate the cloud. $\endgroup$ Apr 11 at 12:13
