      it’s the ones not in the ocean ***yet*** that are most concerning.

      … don’t stare at your feet all day.

      Planetary Defense at NASA

      In 2016, NASA established the Planetary Defense Coordination Office (PDCO) to manage the agency’s ongoing mission of finding, tracking, and better understanding asteroids and comets that could pose an impact hazard to Earth. Here you can stay informed about the PDCO, NASA’s Near-Earth Object (NEO)  Observations Program, and upcoming planetary defense flight missions, including NASA’S NEO Surveyor mission.

      Impt to note the impactor in this case had a diameter of 600m, compare that to the Chicxulub impactor with a diameter of ten kilometers.

      So the crater is about 1000 feet below sea level. I’m guessing that means it has always been submerged? Or could an ice age lower sea levels that much ?

      People always forget, asteroids bring other asteroids (and associated debris). No one likes to travel millions of miles alone.

      Well thank you scientists for letting us know asteroids are not a one off. I appreciate the time and money spent on this research project.
