What is asteroid 2020nd and why is NASA warning about it?

Asteroid 2020nd is a massive space rock approaching Earth that NASA has classified as potentially hazardous. This asteroid is approximately 443 feet in size, making it about 50% larger than the London Eye landmark in the UK. NASA's warning stems from the asteroid's significant size and its relatively close approach to our planet. The space agency monitors such large celestial objects that come within concerning proximity to Earth, labeling them as potentially hazardous when they could pose a theoretical risk, even if an actual collision is unlikely.
