Fragments of a meteor that lit up the skies of Michigan have been recovered by Arizona meteorite hunters.
A huge meteorite that exploded over Michigan recently produced some fragments that touched the ground, and a couple of meteorite hunters have managed to find them. The fragments fell near the municipality of Hamburg and were discovered by meteor hunters Larry Atkins and Robert Ward, and Ward has found hundreds of fragments in his life.
The meteor was about six feet wide and created an intense glow near Detroit. since it disintegrated 20 miles above the surface of the Earth. Atkins and Ward were able to find the fragments using witness testimony and some help from the Doppler radar.
Atkins and Ward showed the fragment to the media recently, marveled at its composition and the fact that it had spent its life accelerating through the confines of space before reaching its hand.
Here is an excerpt from Wikipedia that explains what a meteor is.
A meteoroid is a small rocky or metallic body in outer space. 19659004] Meteoroids are significantly smaller than asteroids and vary in size from small grains to objects one meter wide. Smaller objects that are classified as micrometeoroids or space dust. Most are fragments of comets or asteroids, while others are impact collision particles ejected from bodies such as the Moon or Mars.
When a meteoroid, comet or asteroid enters the Earth's atmosphere at a rate typically greater than 20 km / s 72,000 km / h; 45,000 mph), the aerodynamic heating of that object produces a ray of light, both of the bright object and the trail of bright particles left behind. This phenomenon is called meteorite or "shooting star". A series of many meteorites that appear seconds or minutes apart and that seem to originate from the same fixed point in the sky is called meteor shower. If that object resists the ablation of its passage through the atmosphere like a meteor and hits the ground, then it is called a meteorite.
Each year, 15,000 tons of meteoroids, micrometeoroids and different forms of space dust enter the Earth's atmosphere.
Almost all meteoroids contain extraterrestrial nickel and iron. They have three main classifications: iron, stone and stony iron. Some stone meteoroids contain grain-like inclusions known as chondrules and are called chondrites. Stony meteors without these characteristics are called "acondrites", which are typically formed from extraterrestrial igneous activity; they contain little or no extraterrestrial iron.  The composition of meteoroids can be inferred as they pass through the Earth's atmosphere from their trajectories and the light spectra of the resulting meteor. Its effects on radio signals also provide information, especially useful for daytime meteors, which are otherwise very difficult to observe. From these trajectory measurements, it has been found that meteoroids have many different orbits, some are grouped in currents (see meteor showers) often associated with a major comet, others apparently sporadic. The debris from the meteoroid streams can eventually disperse into other orbits. The light spectra, combined with the trajectory and the measurements of the light curve, have produced several compositions and densities, ranging from fragile objects similar to snowballs with a density of approximately one quarter that of ice, to dense rocks rich in nickel and iron. The meteorite study also provides information on the composition of non-ephemeral meteoroids.
Remarkable Meteorites: The Chelyabinsk meteor was an extremely bright explosive fireball, known as superbolide, measuring between 17 and 20 meters in diameter, with an estimated initial mass of 11,000 tons, when the relatively small asteroid entered the atmosphere of the Earth.  It was the largest natural object that entered the Earth's atmosphere since the Tunguska event in 1908. More than 1,500 people were injured mainly by broken window glass caused by air bursting approximately 25-30 km above the windows. surroundings of Chelyabinsk, Russia, on February 15, 2013. An increasingly bright streak was observed during the morning with a long persistent wake. In no less than 1 minute and until at least 3 minutes after the object reached its peak in intensity (depending on the distance of the path), a commotion burst was heard that shattered the car's windows and alarms, what was followed by several smaller explosions.
