The agency is planning a variety of social media events to mark the passage, and allow the public to listen in to scientists as they debate and discuss what they are learning from the fly-by.
For more than a decade the program has run Sentry — a computer system that automatically analyses constantly updated astronomical data, looking for asteroids or other objects that might be on a collision course with Earth. Continue reading via The Washington Times...
