Apophis Asteroid to Cause ‘Astroquakes’ in 2029: What Earth’s Gravity Will Do to the ‘City-Killer’ Rock
A possibly catastrophic asteroid named Apophis will reach its closest approach to Earth in just five years, about 19,000 miles away from our planet. Scientists believe that during this flyby Earth’s gravity could cause the asteroid to undergo what is known as “astroquakes,” or strong shaking or vibrations brought on by gravitational forces. These strong forces should fundamentally change the …
