According to a leading planet formation model known as core accretion, gas and dust particles within these disks glom together into larger and larger bodies. Over millions of years, these bodies smash together and build up into full-size planets, with the biggest objects capturing huge, gassy atmospheres before the protoplanetary disks completely dissipate. However, this core accretion model does not work well at creating gas giants in either tight or very distant orbits from their stars. Nor is the accretion process itself well understood. Newer planet formation theories propose that gas giants can migrate in their orbits, toward or away from their stars as a solar system dynamically evolves. In the process, numerous fledging worlds are gravitationally flung out of the solar system or displaced into unusual orbits.
