Israelis currently own 10 percent of the privately owned land on the moon, where real estate sales have skyrocketed following NASA's announcement last month that it would establish a permanent moon colony by 2025.

While it is illegal under the terms of the United Nations' Outer Space Treaty for states to purchase land in space, private citizens are permitted to do so.

In the 1970s, an American by the name of Dennis Hope took advantage of that treaty and relevant land registry laws to register the moon and all other planets in the solar system except for earth under his name.

Hope has for years been selling plots of 5,000 square feet on the moon for the low price of $60 through his Internet-based franchise Crazyshop.

December saw a significant worldwide boost in sales following the NASA announcement. Nowhere did the sales increase as much as in Israel, where 1,000 new customers bought a piece of the moon.

According to Crazyshop spokesman Tom Wegner, of the 10 million acres of the moon currently owned by private citizens, one million acres is owned by Israelis.

Wegner told The Jerusalem Post that while most view the moon plots as a relatively inexpensive and very unique gift, many also recognize the purchase as "a great investment that their grandchildren might benefit from."
