US detects huge meteor explosion over the Bering Sea
https://www.bbc.co.uk/news/science-environment-47607696
The blast was the second largest of its kind in 30 years, and the biggest since the fireball over Chelyabinsk in Russia six years ago.
But it went largely unnoticed until now because it blew up over the Bering Sea, off Russia's Kamchatka Peninsula.
The space rock exploded with 10 times the energy released by the Hiroshima atomic bomb.
Lindley Johnson, planetary defence officer at Nasa, told BBC News a fireball this big is only expected about two or three times every 100 years.
At about noon local time on 18 December, the asteroid barrelled through the atmosphere at a speed of 32km/s, on a steep trajectory of seven degrees.
Measuring several metres in size, the space rock exploded 25.6km above the Earth's surface, with an impact energy of 173 kilotons.

From the article"That's another thing we have in our defence, there's plenty of water on the planet."
Hardly. A meteor of sufficient size landing in one of the oceans will create a vast tidal wave which will sweep inland causing a massive amount of death and destruction.
(Or, if you're a flat-earther, will spill over the edges of the planet)

Revealed: First image of huge meteor explosion over Earth last yearhttps://www.newscientist.com/article...rth-last-year/
Simon Proud, an aviation safety fellow and meteorologist at the University of Oxford, who shared the image on Twitter, said, “I’m sure it’s the meteor trace.”
He said, “It appears in the images at the right time, it is in the right location, the smoke column is almost vertical, and the smoke is very high. Much higher than any clouds in that region and too high to be a contrail.”
But it could wipe out a city if it made contact .....

I think not, it would cause too much panic. They only have to mention a petrol shortage and the pumps would sell out in an afternoon....
Throughout history there have been some major meteor strikes including the one that wiped out the dinosaurs after the dust from the incident plunged the world into a twenty year winter of darkness.....
I believe the next one is overdue and it will make all this save the world rubbish irrelevant.......

According to the article it happens 2 or 3 times every hundred years and was detected by a Japanese satellite.
