For more than 35 years, Dennis Hope has been selling land on the Moon. Hope registered a claim for the Moon in 1980 and, since the US government & the UN didn’t object, he figures he owns it (along with the other planets and moons in the solar system).

“I sent the United Nations a declaration of ownership detailing my intent to subdivide and sell the moon and have never heard back,” he says. “There is a loophole in the treaty — it does not apply to individuals.” The US government had several years to contest such a claim. which they never did. Neither did the United Nations nor the Russian Government. This allowed Mr. Hope to take the next step and copyright his work with the US Copyright registry office. So, with his claim and Copyright Registration Certificate from the US Government in hand, Mr. Hope became what is probably the largest landowner on the planet today.

An acre-sized plot of the Moon is currently available for $24.99 and Hope says he has sold over a billion acres of his celestial properties to more than 6 million people, including to such moonsteaders as George H.W. Bush, Ronald Reagan, and Star Trek cast members.
