Centauri IV is a rocky world with one interesting feature: it completely lacks a molten core. As a coreless world, the planet never developed an electromagnetic field and was never able to retain a serious atmosphere (archaeological studies have revealed that it had a limited atmosphere for some time, but that solar wind impacts ultimately fully eliminated it roughly three thousand years ago). Due to its proximity to the system’s asteroid belt, Centauri IV has been heavily impacted by asteroidal strikes. The world is considered a potential candidate for terraforming, albeit a very poor one: the need for special technology and resources to construct a core would be an incredibly expensive and technically difficult proposition.
