The asteroid that could destroy us as soon as it passed by the Earth: Where's NASA?

The mass of asteroids on earth can end life. The little ones who can do significant damage are hard to detect. On Thursday, an asteroid called 2019 OK, which was flying 15 miles a second, was unusually close to hitting Earth, writes VOX, [...]
On Thursday, an asteroid called 2019 OK, which was flying 15 miles a second, was unusually close to hitting Earth, writes the VOX, translates Periscope. The Asteroid passed only 43 thousand and 500 miles from land and was closer than the moon.
If you had wax you could see 2019 OK in the sky.
NASA tracks large asteroids that are hard to identify and that may be in a land-crazing trajector. But 2019 OK was first seen a few days earlier, and was definitely identified as asteroid just yesterday hours after it passed by us.
How did they miss it? Astronomer Allan Duffy said that the asteroid could hit the earth with 30 times as much energy as the atom bomb in Hiroshima and that it had the power to wipe out a city from its surface. /Periscope
