The BBC has an article about a man who claims to own the moon.
From his office in Nevada, entrepreneur Dennis Hope has spawned a multi-million-dollar property business selling plots of lunar real estate at $20 (£10) an acre.
Mr Hope exploited a loophole in the 1967 UN Outer Space Treaty and he has been claiming ownership of the Earth's Moon - and seven planets and their moons - for more than 20 years.
There are other moves afoot to coomercialize the moon:
Data collected from the Apollo Moon landings have indicated that large deposits of an extremely rare gas called helium 3 are trapped in the lunar soil.
Scientists believe that this helium 3 could be used to create a new source of almost inexhaustible, clean, pollution-free energy on Earth.
One of them is Dr Harrison Schmitt, a member of the 1972 Apollo 17 mission and the only trained geologist ever to walk on the Moon.
"A metric ton of helium 3 would supply about one-sixth of the energy needs today of the British Isles," he claims.
The Moon, claims Professor Jerry Kulcinski of the University of Wisconsin-Madison, could become the Persian Gulf of the 21st Century.
"If we had gold bricks stacked up on the surface of the Moon, we couldn't afford to bring them back. This material - at several billion dollars a tonne - is what makes it all worthwhile."
