NASA Refines Asteroid Apophis' Path Toward Earth - NASA Jet Propulsion Laboratory

NASA Refines Asteroid Apophis' Path Toward Earth - NASA Jet Propulsion Laboratory: "the asteroid is expected to make a record-setting -- but harmless -- close approach to Earth on Friday, April 13, 2029, when it comes no closer than 29,450 kilometers (18,300 miles) above Earth's surface." Harmless? Consider approximately 200 TV & telephone satellites orbit at 22,000 miles.
