Asteroids, including those in the asteroid belt, have been suggested as possible sites of space colonization. [1] Motives include the survival of humanity, and the specific economic opportunity for asteroid mining. Obstacles include transportation distance, temperature, radiation, lack of gravity, and psychological issues.
Before 1970, asteroid mining existed largely within the realm of science fiction. Publications such as Worlds of If, [8] Scavengers in Space, [9] and Miners in the Sky [10] told stories about the conceived dangers, motives, and experiences of mining asteroids.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
The economic potential of space exploration goes beyond just mining asteroids. McKinsey predicts that the global space economy will grow from $630 billion in 2023 to $1.8 trillion by 2035, even ...

Mining the Sky: Untold Riches from the Asteroids, Comets, and Planets, is a 1997 book by University of Arizona Planetary Sciences professor emeritus John S. Lewis that describes possible routes for accessing extraterrestrial resources, either for use on Earth or for enabling space colonization. [1]
outer main-belt (a > 2.82 AU) A plot of inner solar system asteroids and planets as of 2006 May 9, in a manner that exposes the Kirkwood gaps. Similar to the position plot, planets (with trajectories) are orange, Jupiter being the outer most in this view. Various asteroid classes are colour coded: 'generic' main-belt asteroids are white.
