Asteroid warning: NASA detects a 1KM rock that could kill millions on rapid approach

When this happens, the rock will swing by the planet at speeds of about 15.19km per second or 35,567mph (57,240km/h).

Based on its observations of the rock’s trajectory, NASA estimates the asteroid measures somewhere between 1,443ft and 3248ft (440m to 990m) in diameter.

At both ends of the scale, any impact with the asteroid could be absolutely devastating.
