Large asteroid narrowly misses the Earth

An asteroid the size of a warehouse passed our planet at the weekend just hours after it was first spotted.
Known as Asteroid 2018 GE3, the space rock was several times larger than the meteor that exploded over Chelyabinsk, Russia, which caused widespread disruption and injuries back in 2013.

Worryingly, it was discovered by the Catalina Sky Survey and Steward Observatory in Arizona mere hours before it passed us by at around half the distance between the Earth and the Moon.
At up to 400ft across, the object is much larger than the asteroids that typically pass within this distance and is among the largest to have ventured this close to our planet in recent memory.

Its discovery highlights just how vulnerable we still are to unexpected asteroid strikes.

True, Waspie.. but... in the heat of the moment, if a meteorite struck a key area at a sensitive time, would anyone BELIEVE that it wasn't the Americans/Russians/French ? On the grounds of... "oh that would be TOO much of a co-incidence". The conspiracy theorists would immediately suggest that "the other side" had deliberately influenced the trajectory of a meteorite, or had a stock of them in orbit ready to launch at ground targets.

Don't be paranoid. So you really think that some random person would just push a button and start amageddon on a whim? In the real world there are procedures and chains of command. Massive nuclear retaliation would be ordered in the case of the detection of a mass launch from the enemy. Asteroid reentry = no launch =:no massive retaliation. I was exactly such fears of an accidental nuclear war that led the USA and Soviet Union to develop the satellites which can differentiate between meteors and warheads in the first place. Chelyabinsk is proof that the systems work.

Well, good then And of course, Pakistan and Iran have access to these satellites... so if one of THEIR military bases (or cities) was massively damaged during a period of high tension, they would ALSO calmly analyse the explosion, and not be suspicious or paranoid, and resist knee-jerk reactions. Excellent. Umm.....

Space rock detected mere hours before passing Earth??? I thought we had better technology than that, guess I'm wrong.

Random person? Are we forgetting who the President is? No he would never just drop bombs on a whim... in the real world there are procedures and chains of command? Thats a lovely notion and all but a choice time to say such a silly thing. An asteroid starting nuclear war is silly too but very plausible200 years ago had nukes existed.

Except Pakistan, whilst having nuclear capability, have no nuclear missiles deployed.

Had you bothered to read and comprehend the previous posts in this topic you would have realised that was EXACTLY the point I was making. And no I haven't forgotten who the president is... I don't have one.

Okay, further research shows that this is not quite true, they are however in storage and not capable of the kind of knee jerk reaction you refer to. Pakistans nuclear capability is limited to tactical nuclear weapons and so. whilst being able to strike targets in India they are not capable of causing global nuclear catastrophe. Now is there actually any chance of an ON topic post?

Relax Waspie_Dwarf; I've solved the problem. I've written to my MP asking him to table a draft bill in Parliament requiring ALL asteroids, meteors and comets to register with UK ATC prior to entering the atmosphere. (on pain of a fine). Sorted !

nope! they rather waste it on stupid wars over oil and religion, imagine a world without war and how much we could accomplish
