This touches on an ontological issue that concerns me for several reasons: possible worlds.

Consider the planet Venus in each of the Sci-Fi novels in which the planet is described - it can have different properties, therefore is in fact a different individual.

That is *far* from clear. Suppose in one story it simply lacks a single grain of sand that it actually has. I'm certainly not inclined to say it is a different individual.
