A skyscraper-size asteroid flew closer to Earth than the moon — and scientists didn't notice until 2 days later

Loved reading this part. All I could think was how well the money "we" put out is paying off! Astronomers didn't catch wind of the building-size rock until July 15, when a telescope in South Africa — part of the Asteroid Terrestrial-impact Last Alert System (ATLAS), an array of telescopes designed to spot asteroids several days to weeks before any potential impact — caught the rock making its exit from our neighborhood.

It was hidden in the glare of the sun. Who wants to volunteer to point telescope at the sun and look at it?

14 miles per second - that is slow. Earth is rumbling along at around 18 mps.
In comparison to what? That makes a difference. It was flying from the sun toward the earth - going the opposite direction. That may happen again and will be a whale of an impact!
