99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
Apophis to make 2029 flyby to Earth. Apophis is projected to pass within 20,000 miles of our planet’s surface on April 13, 2029. For the superstitious lot, yes, that's a Friday, no less.
In a bit of ominous news befitting a Friday the 13th: It turns out that the asteroid Apophis could have a very small chance of colliding into Earth in five years, when it is expected to make a ...

For example, it was estimated there was a high chance of 99942 Apophis swinging by Earth in 2029 with a 10 −4 probability of returning on an impact trajectory in 2035 or 2036. It was then determined that a deflection from this potential return trajectory, several years before the swing-by, could be achieved with a velocity change on the order ...
After delivering an asteroid sample to Earth Sunday, the newly expanded OSIRIS-APEX mission is heading to Apophis. The asteroid will come within 20,000 miles of Earth in 2029.
