Craters on earth and moon

There are a lot of craters seen on the moon and also on the earth for example the Barringer Crater
What happened to the meteor that created the crater
The moon too has many craters where are the meteors

Vaporized or extremely fragmented. Event a little research could have told you that without asking.
Also, given the very high velocity, they can make deceptively large craters. A large crater may have been made by a small, but very fast meteor.
In both the case of Earth and moon, these meteors got vaporized or fragmented after impact. Remember that these meteors hit the earth or moon with extremely high speed and they are destroyed after impact. In case of earth the size of meteor is also reduced by burning in the atmosphere when they hit earth's atmosphere.
Good question.. I was also thinking that one before Smile
maybe because we got influenced with the alien meteors on sci fi movies where some object is left found in the crater Smile
Here are some photos I took of carters Catharina, Cyrillus and Theophilus on the moon
The photos were taken with 6 Inch Dobsonian Skywatcher Newtonian Reflector
Diameter of Primary Mirror: 153mm, Focal Length: 1200mm, Resolving Power: 0.74, Focal ratio: F/7.8
Photographed with a digital eyepiece
Imaging Sensor: 1/4 Inch 1.3 Megapixel CMOS, Pixel Size 2.8μm x 2.8μm, Sensitivity: 1.0 V/Lux-sec, Spectrum response 400nm - 1000nm
Image resolution: 640X480
The title story in "bild der wissenschaft" (my favorite German science magazine) 03/2012 was about "cosmic bombs" and craters. Whether or not a meteorite will reach earth surface also depends on the angle when it hits atmosphere.
The largest meteorite crater on earth is Vredefort in South Africa with a diameter of 300 kilometer, 2023 million years old. No meteorite ever has been found causing this crater ( which is true for almost all other famous large craters ).
The youngest meteorite crater is Carancas in Peru with a diameter of 14 meters, created in 2007 by a 15 kilogram meteorite. This impact has been seen by human beings and the only other impact seen by people was the Sterlitamak event in Russia, happened in 1990, where a 325 kilogram ferric meteorite reached the surface of our planet.
5185 craters with a diameter more than 20 kilometer are known on Moon. 182 impact craters are known on Earth, nevertheless most have been gone meanwhile due to erosion and plate tectonics.

They also had a nice chart in their article showing impact interval in years by meteorite size. According to this a meteorite of size 0.01 kilometer or less hits us every 1000 years, causing an impact with an energy somewhere between the Tunguska event and an explosion of a Hiroshima type atomic bomb in the atmosphere. A meteorite of size 1 to 10 kilometer reaches us every 0.1 billion years. A meteorite of such size is said to have caused the distinction of the dinosaur. And of course we have probably no clue what such type of event would mean for our modern civilization.
