Asteroid deflection technologies

Asteroid deflection technologies are methods and strategies developed to prevent potential impacts of asteroids with Earth. These technologies aim to alter the trajectory of an asteroid to ensure it does not collide with our planet Following the success of NASA's DART (Double Asteroid Redirection Test) mission, discussions about planetary defense and asteroid deflection strategies are increasingly prominent. Here are some principal methods and how they work: 1. Kinetic Impactor:    - How It Works: This method involves sending a spacecraft to collide with an asteroid at high speed. The impact changes the asteroid's velocity and trajectory, ideally enough to avoid a collision with Earth.    - Example: NASA's DART (Double Asteroid Redirection Test) mission successfully demonstrated this technique by impacting the moonlet Dimorphos in 2022. 2. Gravity Tractor:    - How It Works: A spacecraft positioned near an asteroid uses its gravitational pull to...

Mile-wide, potentially hazardous asteroid 2003 SD220 to swoosh by Earth on Saturday

A potentially hazardous asteroid (PHA), designated 2003 SD220 (or 163899), is expected to fly by the Earth on Saturday, December 22, at around 1:04 UTC. The space rock, estimated to be about a mile wide (1.6 kilometers), will pass by our planet at a distance of approximately 7.34 lunar distances (LD), what corresponds to 1.75 million miles (2.81 million kilometers).
