Asteroid passing close to the Earth
 
Asteroid 2023 BU will pass closer to the earth than some satellites.

It will pass over the southern tip of South America just after midnight GMT.

A pity in a way that it isn’t going to hit - a rock that size would make a spectacular fireball but not pose any significant threat to anyone on the ground.

Yea it would be interesting if it splashed down in the ocean somewhere.....

Is this the green comet we can see tonight, or something else?

It was something else, it flew past and was gone on the night of the 26th.

Another one this weekend.

Yep, just under 110,000 miles is pretty close.

Crazy that they only noticed it a year ago, it'll be back near missing again next year to

In galactic terms it’s less than a hair’s breadth. It’s worth remembering though that on a planetary scale, the chances of a city-killing meteorite actually landing close to a major population centre are pretty low. Most of the surface is water and most of the land is uninhabited.

Unfortunately, the water part is still a bit of an issue, as any hitting an ocean would cause a tsunami.

Tell that to the dinosaurs.

That was an extinction event rather than a mere city-killer … their space rock was likely 50 or 60 times bigger than this one.

Re: Asteroid passing close to the Earth
 
It's not the size that matters as much as the velocity of impact. KE = 1/2 mass times the square of the velocity. Any rock hitting us is bad news.

(Incidentally, that's why, in some areas, the speed limit was lowered from 40mph to 30. Reason: square 30, you get 900...but square 40 and you get 1600, i.e. nearly double the kinetic energy. This is why impacts at 30 are so much more survivable...and why motorways are so dangerous if things go wrong.)

We definitely need Spaceguard to spot these wayward rocks sooner. Come back, Clarke, all is forgiven.
