Unistellar- Planetary Defense
Planetary Defense entails detecting, monitoring, understanding, and mitigating near-Earth objects. They are small objects in our solar system like asteroids and comets that come close to Earth. For the near-Earth objects that may impact Earth, Planetary Defense involves preventing or mitigating their impact.
In the rare event that a near-Earth object hits Earth, we need to be prepared to prevent it from happening or mitigate its impact. This program uses existing data sets which citizen scientists look for asteroids (near earth objects) and log these on the database.
Another citizen science project on this site is identifying exoplanets.
