Apophis, a 900-foot asteroid, was believed by scientists to have a greater than 2 percent chance of hitting earth.
The asteroid appeared ready to give the Earth its closest shave since astronomers began looking for such things. It was judged a 4 on the Torino Impact Hazard Scale for a short time, the highest rating any near-Earth object has received.
Scientists have since scaled back their predictions -- they now believe the odds of it crashing into earth are 1 in 250,000 -- but astronomers do expect it to come startlingly close to the earth's surface, whizzing past our planet just 18,300 miles away in April 2029.
The Jet Propulsion Laboratory has created a simulation of the asteroid's path past earth. See it in action (from Apophis' perspective) below.
