This process described above assumes that all objects involved are completely spherical, which may not be the case. The act of tearing apart a solid moon, perhaps into rough gravel, might add microvoids to the new layering that bulk up the volume slightly. But neither are gravitational compression effects taken into account on an originally loose material; the planet's gravitational pull could settle some of the moon material into a slightly smaller volume than the one it occupied as lower-gravity moon. | This process described above assumes that all objects involved are completely spherical, which may not be the case.

One could imagine a spherical shell of moon matter around Jupiter with such high structural strength as to resist crumbling into its gaseous maw. Alternatively, the moon material could be expected to sink towards the gaseous planet's centre until it reaches a layer sufficiently dense and/or rigid to stop it sinking further. In this case the moon material would displace a volume of the planet's gas causing an increase in the planet's radius. |
