The building of the planetary defense system (PDS) against asteroid and comet nucleus impact hazards will require adequate international legal instruments that may take the form of an international treaty "On the principles of ensuring the Earth's defense against asteroid and comet nucleus impact hazards".
This report reviews the basic elements of the approach to forming this treaty. More specifically, the treaty should contain principles governing the establishment and use of a security fund of humanity with the aim to financially supporting the development, exploitation and modernization of the system.
It is noted that the United Nations could coordinate the PDS formation and exploitation. For this purpose we need to establish under the aegis of the United Nations an international planetary defense center and its regional offices.
The report provides an explanation for the necessity of reservations to be introduced into some international space law provisions with respect to the issue of the PDS formation, management, and application. In particular, it regards the issue of mitigating hazardous celestial bodies by means of nuclear devices.
