Asteroid Zoo
Asteroid Zoo was a citizen science project run by the Zooniverse and Planetary Resources, to use volunteer classifications to find unknown asteroids using old Catalina Sky Survey data. The main goals of the project were to search for undiscovered asteroids in order to protect the planet by locating potentially harmful near-Earth asteroids, locate targets for future asteroid mining, study the Solar System, and study the potential uses and advantages of crowdsourcing of astronomical data analysis.
