Incoming Asteroid

[Jasey_]

Apparently there's going to be a close pass tomorrow.

Love the take from these different publications

Well, Buckingham Palace is bigger than a bus..

[Mammasaid]

Well, if you call 5,000,000,000 m close...

Asteroid 2018 FK5 is the only known asteroid flying by Earth today that NASA already knew about long before its arrival. This rock is also the most distant one: passing more than 3 million miles (5 million km) from Earth tonight at 6:56 p.m. EDT (2256 GMT). Astronomers at Mt. Lemmon discovered this 24-foot-wide (7 m) asteroid just two days before it flew by Earth in March 2018.

Edit (confused metres with miles!)

You may need to edit your post (slightly too many zeros).

"2019 SP3 will miss Earth by just 231,690 miles" from my link.

According to Americans that's nearer than eye-rack is to the USA

Oh god, the Express.

Point them at this

Then point them at this

Note that craters are not left on water...........

Then watch the Express readers implode.

I really sniggered at this, I still am.

[Zirconia]

Any youngsters need angst on PH for the coming years?

Note the odds, not dead cert but what the heck. Looks like doomy stuff. Red tops can make good work of it.

Of course that is the stuff they have detected, sometimes they wizzes by announced.......

This will likely hit in a remain area so whilst damage to the infrastructure may be severe the amount of intelligent people wiped out will be minimal.
I'm kidding but as its the norm to bring Brexit into everything I thought I'd get in first

Au contraire - asteroids are very good at wiping out dinosaurs, so Brexiteers - be very, very afraid.

Funnily enough I was going to say in the OP this is maybe what all the Brexit pish has been trying to hide.

But decided I've had so much of Brexit even jokes are wearing thin

[sparks_190e]

So how big does an astroid need to be to cause worldwide devastation? I'd wager much bigger then Buckingham Palace!

[Eric Mc]

Depends on a number of factors. Size is obviously one. The speed of impact, the angle of impact and the place of impact all make a difference too.

And composition. There is a handy calculator somewhere. Links above give some reference to the scale used. and potential energy released.

Edit. Cannot find the one I tried a few years ago.
Lots of rubbish comes up in the search but his one is Perdu, seems to be pucker. Mess around with the numbers. Cannot find Liz's gaff in the pre selects though.
