An extinction level event from an asteroid impact is among the most common cause of extinction for many species in the history of life on Earth. Neil deGrasse Tyson explains in detail the possibility of an asteroid impact from the asteroid named Apophis after the ancient Egyptian deity who embodied chaos, its estimated diameter is between 1,115 and 1,214 feet. Additional observations cleared up the concern of a direct impact. Apophis is expected to pass close to Earth in 2029, 2036 and again in 2068. Neil deGrasse Tyson explains the details if Apophis were to hit near the coastline of North America. Asteroids are rocky fragments left over from the formation of the solar system about 4.6 billion years ago. Most of the asteroids orbit between Jupiter and Mars, where the Jupiter's gravity prevents them from ever combining into a larger body.
