What percentage of a meteor would burn up as it passes through the Earth's atmosphere?

[Matthew]

If, hypothetically, a mile wide meteor was passing through the Earth's atmosphere, what percentage of it would actually reach the ground? I know that the meteors the size of houses are disintegrated to small rocks, which would mean that more than 90% of the meteor would disintegrate, but does the percentage decrease substantially as the size increases? The Chickxulub Crater, the one that is believed to wipe out the dinosaurs is approximately 110 miles in diamter. But I've researched that the the size of the meteor is generally one twentieth of the size of the crater due to the force and speed of the meteor at impact. If that is true, that would mean that the meteor is approximately 5.5 miles in diameter. But what would the size be as it travels in space? I'm just curious because I am in the process of writing a trilogy.

This is my second book, my first novel, "Fall Of The Empire" will be published as an ebook in a couple months. For information about my new book and all upcoming books, free podcasts of chapters of my novels, as well as other information follow me on twitter @MatthewLeasa

I just started twitter as a tool for advertisement, and to connect to my fans, so any followers would be greatly appreciated

Thanks to everyone who takes the time out to answer my question.

There are just too many variables involved to nail down any specific, etched-in-stone figures. Just some of the considerations -- density of object, its composition, velocity, angle of flight, etc.,

P.S.
Congrats on your new book.

First congratulation on your book, I will defiantly check it out.
Now on to the meteors. We are surrounded by the asteroid belt. A lot of them fall on earth, but like you said, easily burn up in the sky. I don not now a percentage for sure, but I can provide you with some info. Yes, the bigger a meteor the less chance it will burn up and meet earth. But I want you to know that even if a big meteor burn up, it cold be bad news. It could burn up and explode in the sky, causing a similar effect like an atomic bomb

There are too many variables to answer your question. However, here's a link to a really neat meteor impact simulator that should be able to help you out.

It depends on the speed and direction of the incoming object and how strong it is. If it is a weak ball of dust it could be quite large and completely disintegrate in the air, but if it is a small blob of nickel-iron it might loose very little mass before hitting the ground. If it comes in slowly enough it might loose almost none of it's mass. For example space craft like the Shuttle are designed to get hot without loosing any of their mass and they enter the atmosphere at a very shallow angle and a slower speed than a meteor. The Apollo capsules returning from the Moon hit the atmosphere at the same speed as the slowest possible meteor but also did so at a very shallow angle and so that only a tiny percentage of the mass of the heat shield was lost.

The result would depends on several things. Basically, the final crater would have a diameter of 21 km and a depth of 740 meters. I don't know how much of the meteor would burn/melt/vaporize in the atmosphere before impact, but it would be very little compared with the whole thing. The meteor spends only 6 seconds in the atmosphere, so I would expect that less than a meter would burn off. Certainly less than 0.2%, as long as the meteor doesn't breakup.

There would be mass fatalities out to about 300 km (190 miles).
