  Throughout recorded history, humans have crossed national borders to seek
safety in nearby countries. The reasons for displacement have been generated by
phenomena of terrestrial origin, but exposure to unexpected extra-terrestrial
threats poses a different scenario. An asteroid impact warning implies a change
of paradigm which would represent a historic precedent. In this regard, the
analogies with natural disasters must be considered, along with multiple
possible scenarios, and legal aspects related to a) the legal framework to
regulate this situation; b) the action and responsibility of the states; and c)
the definition of impact refugee and the reconfiguration of traditional
concepts such as deterritorialized states. In addition, the decision-making
process and the actors involved must be led by a cooperative effort to improve
international law. These new circumstances should be established with a
consideration of inequalities between the states, and an aim of protecting
humanity through democratic solutions using the safest, most effective
techniques.
