Asteroid impact 2029

Asteroid Aphopis is coming to Earth ! Will it hit our planet?

More than 100,000 asteroids hurtle past our planet. But only one—the one detected so far—may hit us in the next 30 years. Apophis, the ancient Egyptian god of darkness.

Detected in 2004 , all alarms went off, the calculations indicated that he could hit earth on Friday the 13th of April 2029. Further observations showed that will not happen. Scientists are 99.7 percent certain it will pass at a distance of 18,800 to 20,800 miles. In astronomical terms, 20,000 miles is a mere stone’s throw, well inside the orbits of Earth’s many geosynchronous communications satellites.

However, and here is the bad news, scientists calculate that if Apophis passes at a distance of exactly 18,893 miles, it will go through a “gravitational keyhole.” This small region in space–only about a half mile wide, or twice the diameter of the asteroid itself–is where Earth’s gravity would perturb Apophis in just the wrong way, causing it to enter an orbit that will will put earth on its way and set potentially catastrophic asteroid impact precisely seven years later, on April 13, 2036.
