Large Asteroids with the Potential to Destroy an Entire Country or Continent have been Detected

Science Today: B612 Foundation Sentinel Earth is continuously colliding with fragments of asteroids, the largest in recent times exploding over Tunguska, Siberia, in 1908 with an energy impact of 5-15 megatons. More recently, we witnessed the 600-kiloton impact in Chelyabinsk, Russia, in 2013, and asteroid impacts greater than 20 kilotons occurred in South Sulawesi, Indonesia, in 2009, in the Southern Ocean in 2004, and in the Mediterranean Sea in to note as well is the fact that none of these asteroids were detected or tracked in advance by any existing space-based or terrestrial observatory."While most large asteroids with the potential to destroy an entire country or continent have been detected, less than 10,000 of the more than a million dangerous asteroids with the potential to destroy an entire major metropolitan area have been found by all existing space or terrestrially-operated observatories," "Because we don't know where or when the next major impact will occur, the only thing preventing a catastrophe from a 'city-killer' sized asteroid has been blind luck."The B612 Foundation aims to change that by building the Sentinel Space Telescope Mission, an early warning infrared space telescope for tracking asteroids that would provide many years to deflect an asteroid when it is still millions of miles away. The B612 Sentinel Mission will be the world's first privately funded deep space mission that will create the first comprehensive dynamic map of our inner solar system, identifying the current and future locations and trajectories of Earth crossing asteroids. Sentinel will detect and track more than 200,000 asteroids in just the first year of operation, after a planned launch in more here:
