On Friday, April 13, 2029, Earth will experience a dramatic close encounter with the asteroid 99942 Apophis. The 1,120 feet (340-meter) wide object will pass within just 19,000 miles (31,000 km) of our home planet — a distance that brings it closer than most geostationary satellites.On Friday, April 13, 2029, Earth will experience a dramatic close encounter with the asteroid 99942 Apophis.
