COLORADO SPRINGS, Colorado — Asteroid Apophis is set to whisk by Earth in 2029 and serve as a wake-up call for getting our planetary defense act together.

Astronomers have shown that the huge chunk of extraterrestrial real estate will not hit Earth in 2029, but will come closer to Earth than our geostationary communications satellites. Radar measurements estimate Apophis is roughly 1,500 feet (450 meters) wide and some 550 feet (170 meters) tall. The April 13, 2029 (conveniently Friday the 13th) Apophis passage will be visible to the naked eye and is stirring up considerable multi-nation action plans to spy on the asteroid at various stages as it careens toward Earth, helping scientists plan for possible planetary defense scenarios.
