Planetary defense refers to the strategies and technologies used to protect Earth from potential threats posed by near-Earth objects (NEOs), such as asteroids and comets. These celestial bodies can collide with our planet, causing significant damage. Scientists and space agencies, like NASA, monitor the skies to identify and track these objects, assessing their orbits and potential impact risks. To mitigate these threats, various methods are being developed, including deflection techniques that aim to change an object's trajectory. One notable mission is the DART (Double Asteroid Redirection Test), which tests the ability to alter an asteroid's path by crashing a spacecraft into it.
