   NEO Surveyor will find asteroids and comets that other space missions cannot, filling a critical gap in humanity’s ability to detect potentially hazardous near-Earth objects. In addition to planetary defense, scientists will use data from NEO Surveyor for studies of near-Earth objects to learn more about the evolution of the solar system.

   1 maj 2023 · Near-Earth Objects, or NEOs, are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter Earth’s neighborhood. The Near-Earth Object Program coordinates NASA-sponsored efforts to detect, track and characterize potentially hazardous asteroids and comets that could ...
