The ‘God of Chaos’ asteroid, known as Apophis, is an S-type asteroid that NASA’s OSIRIS-APEX mission is set to study in 2029. This mission aims to observe the asteroid’s close approach to Earth, which will be within 20,000 miles, closer than some satellites. Scientists anticipate that Earth’s gravity will affect Apophis, potentially leading to surface changes like quakes and landslides. This mission is significant for understanding hazardous asteroids and solar system formation, contributing to planetary defense research.
