What a crazy coincidence. Last night I uploaded three videos on asteroid and comet impacts. This morning we had an extremely close call. Asteroid 2019 OK missed Earth by 0.19 LD (72,000 km; about 6 Earth diameters; 19% of Earth-to-Moon distance). Asteroid diameter was between 57 to 130 meters, speed 24.5 km/s. Upper end size would hit with an energy of 260 MT (17,000 Hiroshima size bombs), causing a 2.6 km diameter crater 556 meters deep. The fireball would have been 1.5 km in diameter, and the frequency of occurrence is about once every 12,000 years. An extremely close call; and a total surprise.
