Did you know that a meteor recently hit earth and we were completely unaware of it? And I don't just mean us the common people. What I mean to say is "we" as a species including all our governments combined.
Relax though, except for a few unlucky fish no one got hurt, it was the largest we've had since the famous Chelyabinsk bolide that exploded over Russia in 2013.
This summarizes the large-ish meteor impact over the South Atlantic Ocean, that happened on Feb. 6, and was recorded by the Fireball and Bolide Reports page of NASA's Near Earth Object Program.
I just thought you should know that at any given moment you can be hit by an asteroid.
