How did the meteor that hit Arizona get passed the atmosphere?

Answer 1

It was large enough to survive the travel through the atmosphere.

The space rock that carved Meteor Crater in Arizona hit the planet much more slowly than astronomers once figured, but still 10 times faster than a rifle bullet.

The new analysis, announced today, explains why there's a lot less melted rock in the crater than expected. The mystery has dogged researchers for years.

The big hole in the ground -- 570 feet deep and 4,100 feet (1.25 kilometers) across -- was blown into existence 50,000 years ago by an asteroid roughly 130 feet (40 meters) wide.

Answer 2

Earth's atmosphere is an effective but selective screen that prevents smaller meteoroids from hitting Earth's surface The speed and composition of a meteor also come into play. So the answer is it was big, fast and hard.

Answer 3

It depends on speed and trajectory. If a rock is too large, the atmosphere won't stop it. But that's NOT the only possible reason. If the rock comes straight down instead of at an angle, the atmosphere won't stop it either.

Answer 4

it made it through. depending on the size, composition, velocity and angle of entry in the atmosphere an asteroid could may or may not burn up in the atmosphere due to the friction with the air

Answer 5

It is possible that it is not a meteror it may have been a aquafer that dried up and collaps though they sell it for revenue as a meteor.

Answer 6

It must have been HUGE because they mostly burn up as they enter our atmosphere.

Answer 7

large enough, and comprised of ferrous iron

Answer 8

It was big enough to survive.

Answer 9

It was big enough so that all of it didn't vaporize.
