Do we really even need it to be in the sun? Just somewhere orbiting around the sun it's probably not going to do any harm either. Space is big yo.
They said the same about the oceans a few hundred years ago too. Now we have a veritable continent made out of garbage. /hyperbole
Though space is at least a few million orders of magnitude bigger than the oceans...
literally every single proper planet (including pluto) togheter fits between just the earth and the moon though. you're going to need a lot of garbage to create even a decent-sized asteroid.
Including the gas giants?
Yes.
