Danger Above: Tracking Near-Earth Asteroids

With the constant threat of Near-Earth Asteroids (NEAs) looming, tracking and monitoring their trajectories are crucial for protecting our planet from potential impacts.


NEAs are asteroids with orbits that bring them close to Earth, posing a potential danger if their paths intersect with our planet.

NEA Threat

Advanced detection systems, including ground-based telescopes and space-based observatories, play a pivotal role in identifying NEAs and tracking their movements.


Initiated by NASA in collaboration with international partners, the Spaceguard Survey aims to systematically discover, track, and characterize NEAs to assess the risk they pose to Earth.


NASA's Near-Earth Object Program coordinates efforts to detect, track, and catalog NEAs, providing crucial data to inform planetary defense strategies.

Object Program

Sophisticated algorithms and modeling techniques enable scientists to assess the impact risk posed by NEAs, determining the likelihood of a collision.

Risk Assessment

In the event of an imminent threat from a NEA, various mitigation strategies, such as deflection missions or asteroid redirection techniques.


Given the global nature of the NEA threat, international collaboration is essential in tracking and mitigating the risk, with organizations worldwide.


Raising public awareness about the NEA threat is crucial for fostering support for planetary defense initiatives and ensuring preparedness for potential impacts.
