I wonder how big a meteor would have to be before it would actually reach the ground? I suppose it would depend on what it was made of and how fast it was moving. 86,000 miles per hour is kind of quick.

The Barringer meteor crater is one of the best researched and oldest..the statistics are amazing Sky: The object that excavated the crater was a nickel-iron meteorite about 50 meters (54 yards) across, which impacted the plain at a speed of several kilometers per second. Impact energy has been estimated at about 10 megatons. The speed of the impact has been a subject of some debate. Modeling initially suggested that the meteorite struck at a speed of up to 20 kilometers per second (45,000 mph), but more recent research suggests the impact was substantially slower, at 12.8 kilometers per second (28,600 mph). It is believed that about half of the impactor's 300,000 metric tons (330,000 short tons) bulk was vaporized during its descent, before it hit the ground. The impactor itself was mostly vaporized; very little of the meteorite remained within the pit that it had excavated. There's some pics here en.wikipedia.org/wiki/Meteor_Crater

I love that big meteor crater. That thing is one of the coolest things I have ever seen. I've been out there several times to visit it. Can you imagine what that must have looked like as it came screaming down from the heavens? I bet it was a huge explosion! BOOOOMM!!!

when I was about 13 years old, we lived in kingman az. I was observing venus in daylight, and had my telescope out. its visual with the naked eye even during daytime if you know where to look. anyways, I knew where jupiter and saturn was because they were close by so I was observing them too, although I couldnt find them with my eye only with the scope. when I looked up up to try to readjust position with the finder scope, a meteor with a long streak behind it went across the sky and broke up as it was moving along towards the hualapai mountain range !!! this is the only meteor ive ever witnessed in broad daylight, and I can only imagine what kind of fireball it wouldve produced had it been at night. it was quite a site !!!

Where I live a couple of times now..Ive seen meteorites come in from east to west with a cool greenish tint. They always looked like they burned up before hitting but never know..there could be some small fragments hanging around

Ive only seen one meteor in daylight and it was awesome! This was over 30 years ago but I still remember the flaming chunk of rock as it flew past. MDaisy

Here is the video of the daytime fireball that was seen during the 2009 Austin Marathon. That looks like a pretty big chunk of whatever it was. Imagine how that would have looked at night!

I saw my first and only one not long after the ufo armada back in nov. or early dec. last year. It traveled from north to south towards springfield mo. I thought it was going to impact because it just kept traveling towards the ground and my son and his family live in that town. I reported it to mufon with the other encounters but havent heard back.

I saw a green meteorite when that furry critter chased after me. I've seen a couple more since then but that was the brightest.

See how the flashes go off in the sky from it. Do you know why this happened?

The bright flashes are caused when the meteor breaks apart as it is falling. Every time it breaks up it makes a huge flash like that.
