What is asteroid 2020ND and why is NASA concerned about it?

Asteroid 2020ND is a giant celestial body that NASA has identified as potentially hazardous. It's over 50% larger than the London Eye and is approaching Earth, expected to make a close pass at just 0.034 astronomical units from our planet. The asteroid is classified as potentially hazardous due to its size and proximity to Earth's orbit. These celestial objects are particularly fascinating as they are remnants from the formation of our solar system, providing valuable insights into its early development and composition.
