This work investigates the permissibility and viability of property
rights on the - lestial bodies, particularly the extraterrestrial
aspects of land and mineral resources ownership. In lay terms, it aims
to ?nd an answer to the question "Who owns the Moon?" The ?rst chapter
critically analyses and dismantles with legal arguments the issue of
sale of extraterrestrial real estate, after having perused some of the
trivial claims of celestial bodies ownership. The only consequence these
claims have on the plane of space law is to highlight the need for a
better regulation of extraterrestrial landed property rights. Next,
thebook addresses theapparent silenceofthelawinthe?eldofextraterr- trial
landed property, scrutinizing whether the factual situation on the
extraterrestrial realms calls for legal regulations. The sources of law
are examined in their dual dimension - that is, the facts that have
caused and shaped the law of extraterrestrial real estate, and the norms
which express this law. It is found that the norms and rules regarding
property rights in the celestial realms are rather limited, failing to
de?ne basic concepts such as celestial body.
