Asteroid "2020 SW" just missed hitting the earth by 13000 mile today, which is awfully close as the earth itself is 7900 miles in diameter. 2020 SW was as "big as a school bus." I assumed that we weren't warned in advance because NASA was afraid of creating a panic that would cause democrats to riot, loot stores, set fires and and throw water bottles at the police. Still...I would have liked to be warned in advance so that I could go into asteroid survival mode. I have plans for this situation.
