From LiveScience:
Landslides and tremors may transform the asteroid Apophis during its 2029 brush with Earth, according to a new study.
Named after Apep, the ancient Egyptian god of chaos, Apophis is a 1,100-foot-long (340 meters), peanut-shaped asteroid. Although an impact with a space rock that size wouldn’t annihilate our planet, it could easily destroy a city.
