In Egyptian myth, Apophis was the ancient spirit of evil and destruction, a demon that was determined to throw the world into darkness forever. A fitting name, astronomers reasoned, for a threat now rushing towards Earth from outer space. Scientists are monitoring the progress of a 390-metere wide asteroid discovered last year, which is potentially on a collision course with the planet.  NASA has estimated that Apophis has an outside chance of hitting the Earth in 2036. If it did hit us, thousands of square kilometers would be directly affected by the explosion but the whole of the Earth would see the effects of the dust sent into the atmosphere. At a recent meeting of experts in Near-Earth objects (NEOs) in London, scientists said it could take decades to design, test and build the required technology to deflect the asteroid.  The Apophis asteroid is placed at four out of ten on the Torino scale--a measure of the threat caused by an NEO where 10 is a certain collision which could cause a global disaster. This is the most possible danger of any asteroid in recorded history and it has a 1 in 37 chance of hitting the Earth.  Alan Fitzsimmons, an astronomer from Queen's University Belfast, said, "When it does pass close to us on April 13, 2029, the Earth will deflect it and change its orbit. There is a small possibility that if it passes through a particular point in space, the so-called keyhole, the Earth's gravity will change things so that when it comes back around again in 2036, it will collide with us." The chance of Apophis passing through the keyhole, a 600-meter patch of space, is 1 in 5,500, based on current information.  There is no shortage of ideas on how to deflect asteroids. The Advanced Concepts Team at the European Space Agency has led the effort in designing a range of satellites and rockets to nudge asteroids that are on a collision course for Earth into a different orbit.
