What does NASA define as a close approach for an asteroid?
Answer
An asteroid that passes within a certain distance of Earth, which can still be millions of miles away
A close approach is a technical term used by space agencies to categorize the proximity of asteroids relative to Earth. While the term suggests immediacy, the actual distance often remains vast, spanning millions of miles. This classification serves as a tracking mechanism rather than an indicator of an imminent collision. It is essential to understand that these events happen frequently and generally occur within a safe buffer zone, posing no actual threat to the planet.
