"NASA Uncovers Alarming Gap in Identifying City-Killing Asteroids"

NASA has released an infographic highlighting the terrifying gap in our knowledge about asteroid threats. As of August 2023, there are 32,000 known near-Earth asteroids, with over 10,000 of them being more than 140 meters in diameter, capable of wiping out an entire city if they were to hit Earth. However, experts estimate that we haven't even found half of the near-Earth asteroids of this size, with over 14,000 still undiscovered. Additionally, there are around 50 1-kilometer diameter asteroids that we have yet to find. The planetary defense community, including NASA, has a lot of work to do to ensure the safety of humankind from potential asteroid impacts.
