摘要

地球不可能一直适合人类居住，何时离开地球是一个需要思考的问题.考虑到太阳寿命、宇宙射线威胁、地外天体撞击、地球资源开发与环境变化等情况，为人类计算出至少要完成宜居天体寻找、星际航行、星际殖民等技术成熟的最晚期限至关重要.

关键词： 地球；撤离；期限

Abstract

The earth cannot always be suitable for human habitation, and when to evacuate from the earth should be considered. Considering the solar life span, cosmic ray threat, the impact of extraterrestrial objects, and environmental changes, it is essential to calculate the latest expected time for humans to complete the technology for livable planet search, interstellar navigation, and interstellar colonization.

Key words： earth; evacuation; deadline
