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...

Interstellar objects like 'Oumuamua probably crash into the sun every 30 years

On October 19th, 2017, the Panoramic Survey Telescope and Rapid Response System-1 (Pan-STARRS-1) in Hawaii announced the first-ever detection of an interstellar object, named 1I/2017 U1 (aka. 'Oumuamua). In the months that followed, multiple follow-up observations were conducted to learn more about this visitor, as well as resolve the dispute about whether it was a comet and an asteroid.
