 In VGAP3 there was an addon called Asteroids which were immensely rich mineral laden asteroids which everyone wanted. They would appear at random points with a vector and drift through different folks' territories. You had to mine them before they got out of range.

We might just have to wait till Planets 4 opens up to 3rd party add-ons.  Or maybe there is a way Tim can allow some ship hull to tow asteroid fields (Like IMT towing planets)
