In and around our planet, there are thousands of comets and asteroids known as near-Earth objects (NEOs). Multiple space agencies and government affiliates are responsible for tracking them, especially those known as potentially hazardous asteroids (PHA). These objects are so-designated because they will cross Earth’s orbit and may even collide with it someday. Considering how impacts in the past have caused mass extinctions (like the Chicxulub impact event that killed the dinosaurs), future impacts are something we would like to avoid!
