Just a comment/question.  I'm by no means an authority on this, but according to the video (and subsequent research I did on 2018 VP1), it appears to be an asteroid, not a comet.  Also - 2 metric tons, in terms of asteroids hitting the earth - isn't significant.  2018 VP1 is about 2 meters (7 feet) in diameter.  By comparison, the Tunguska meteor that flattened a portion of Siberia, was 65 meters in diameter.  This might be the "sky event" that was predicted.  But an object this small generally burns up/explodes in the earth's atmosphere.
