A team of astronomers from the University of Hawaii is developing a system to indentify dangerous asteroids before their final fall to Earth. According to the researchers, the system will offer a 1 week warning for a 45 meter diameter and 3 weeks for a 140 meter diameter asteroid. “That’s enough time to evacuate the area of people, take measures [...]

A team of astronomers from the University of Hawaii is developing a system to indentify dangerous asteroids before their final fall to Earth.
According to the researchers, the system will offer a 1 week warning for a 45 meter diameter and 3 weeks for a 140 meter diameter asteroid. “That’s enough time to evacuate the area of people, take measures to protect buildings and other infrastructure, and be alert to a tsunami danger generated by ocean impacts,” said John Tonry, principal investigator for the project.
