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.

[3] 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.

[4][5] The project was created along with the ARKYD project through Kickstarter in 2014 and was funded with around 1.5 million dollars raised.

[6] In 2016, the Asteroid Zoo community exhausted the publicly available data, and the experiment was indefinitely paused.

[7][8] Asteroid Zoo produced several scientific publications during its run.
