And it'll be travelling at an incredible speed, since Force = mass x speed (I think) it'll be an incredibly powerful impact if it were to hit, vapourize part of an ocean or something..

Energy is related to mass and velocity2 ( I believe ) so that makes it worse.

with a diameter of 1300 feet it would be like gouging out Ben Nevis and trowing it though space, if it did hit, at that size it would cause us a few problems!

Ben Nevis is 1344 metres high, James, this is 1300 feet - only about one third the height.

You also have to remember that a fair amount of it would likely burn up on entering the earth's atmosphere.

Why, have you really got a hang-over James?   laugh

Off-topic.   How is your dad doing following his operation. Is he home yet?

What we really have to be worried about is the sun.A massive solar storm is expected within 2 years and its already had major but smaller storms causing blackouts across america and satellite comms to be broken.Already the northern lights have been seen as far south as the south coast of the UK and nasa and sun experts are studying the solar activiity big time so we can be prepared.If it happend on a big scale which it could there could be a Global hurricane and severe weather across the globe which is why the weather has been going weird lately all over the place.Back on topic have you seen the crater in arizona it was caused by a meteor the size of a small stone and look what damage that done.But it did not burn up in the atmosphere.

If we cross it's path or vice versa it may come in at 90 degrees vertical and not have time to burn up in the atmosphere, most do come in at an angle since the orbit paths cross at an angle less than right angles. I hope that makes sense. The sun activity can cause all sorts of problems, it can distort the earths magnetic field, causing ions to fly in and cause havoc with electrical things.. Hardhats On! And unplug the TV aerial!...zaappp.... best go out and get some spare fuses... Shocked

Thanks BB, he's been steadily recuperating at the JPH for a couple of weeks now, having a bit of trouble walking but building his strength back up.

I do agree solar storms are a threat to the current human lifestyle that relies so much on satalites, transmitters electricity etc...  but this could be repaired in time unlike the aftermath of a 'big' asteroid hit

Glad to know he's now nearer home and on the mend, James.   Hope he continues to improve and is able to return home, soon.   My best wishes to him.
