Asteroid SHOCK: How astronomers ‘LOST’ 600-mile-wide space rock ‘moving VERY fast’

“People knew there was this small planet, but it was lost for several years until it was discovered again.

“We now call this Ceres.”

The robotic NASA spacecraft Dawn entered orbit around Ceres on March, 6, 2015, to learn more about it. 

However, the space agency is constantly on the lookout for asteroids that may pose a threat to Earth. 

Previously, a scientist admitted he was “absolutely certain” an asteroid similar to what wiped out the dinosaurs would strike again.
