The planet was uninhabitable and had little natural resources that were worth mining.
The planet was initially surveyed during the time of the Old Republic. While the second planet of the system, Kira II - designated Kira Prime, was deemed worthy of further developement, Kira IV was classified as uninhabitable.
When a follow-up survey was conducted several years later, Kira IV was the only planet remaining in the system, while all others had been destroyed by an unknown cataclysm.
