Extraterrestrial real estate

Extraterrestrial real estate is land on other planets or natural satellites or parts of space that is sold either through organizations or by individuals. Ownership of extraterrestrial real estate is not recognized by any authority. Nevertheless, some private individuals and organizations have claimed ownership of celestial bodies, such as the Moon, and are actively involved in "selling" parts of them through certificates of ownership termed "Lunar deeds", "Martian deeds" or similar. These "deeds" have no legal standing.
