Asteroid Terrestrial-impact Last Alert System   


ATLAS is an asteroid impact early warning system developed by the University of Hawaii and funded by NASA. It consists of four telescopes (Hawaii ×2, Chile, South Africa), which automatically scan the whole sky several times every night looking for moving objects.  

ATLAS will provide a warning time depending on the size of the asteroid -- larger asteroids can be detected further from Earth. ATLAS will see a small (~20 meter) asteroid several days out, and a 100 meter asteroid several weeks out. A 100 meter asteroid has approximately 10 times the destructive force of the recent Tonga volcanic eruption.
