Current events NASA asteroid

 An enormous asteroid big enough to leave a six-mile-wide crater and darken the world with dust if it hit Earth went by our planet on April 29. The object, called 1998 OR2 is at least a mile wide, and while it poses no threat it will pass within four million miles of our planet close enough to be classified by NASA as potentially hazardous because it will continue to make close passes to Earth in the future as both objects orbit the sun.

Earth will almost certainly confront a space rock large enough to obliterate a city or worse at some point in its future That’s why NASA is launching a spacecraft next year to conduct the first test of one promising strategy for stopping a killer asteroid Hit it while it’s still far enough away to alter its course.
