This curious little asteroid has made news recently with its very unique orbit. It's speculated that it is of interstellar origin trapped in our system due to the nature of its orbit. BZ509 is of unknown composition, but if from outside our system, it could be one of the most ancient pieces of matter in our solar system.
A 10 square mile claim would be enough for basic mining operations and local support structure. Hypothetical estimated value in 2017 USD $1 trillion. This is a limited release asteroid with the number of available claims limited to only 1.
