The earth gets hit by similarly sized asteroids every 30,000 to 100,000 years, albeit not quite at this velocity. Average impact velocity for asteroids from our system is 17 Km/sec, so about 2/3s the speed of this visitor. Either way, it's not even close to an extinction event.
And "very close to it" is a misnomer. It came within 24 million kilometers of Earth, about 60 times farther away than the moon is.
