Meteoroids are the smallest members of the solar system, ranging in size from large fragments of asteroids or comets, to extremely small micrometeoroids. Meteors were once thought to be a purely atmospheric phenomena, and the study of these and other atmospheric effects, especially weather, spawned the science of meteorology.
If you've spent much time looking up at the night sky, you've probably seen some spectacular meteors and meteor showers. One of the most amazing things about these displays is that the majority of the space dust that causes visible meteors is tiny -- between the size of a grain of sand and the size of a small pebble. Discussing meteor activity can be tricky because the terminology is confusing. The term meteor actually refers to the streak of light caused by a piece of space debris burning up in the atmosphere. The pieces of debris are called meteoroids , and remnants of the debris that reach Earth's surface or another planet's are called meteorites. Meteoroids have a pretty big size range. They include any space debris bigger than a molecule and smaller than about feet meters -- space debris bigger than this is considered an asteroid.
Meteoroids are significantly smaller than asteroids , and range in size from small grains to one-meter-wide objects. This phenomenon is called a meteor or "shooting star". A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. If that object withstands ablation from its passage through the atmosphere as a meteor and impacts with the ground, it is then called a meteorite. An estimated 25 million meteoroids, micrometeoroids and other space debris enter Earth's atmosphere each day,  which results in an estimated 15, tonnes of that material entering the atmosphere each year.
Meteor astronomer Peter Jenniskens must move quickly to trap evidence of a fresh meteorite fall. So Jenniskens traveled to the Nubian Desert to recover fragments, as did dozens of searchers from the University of Khartoum. In April of this year, he did not have to travel nearly so far to gather fresh meteoritic material. The California bolide, like its African predecessor, made a well-documented entrythree Doppler radar stations picked up the track of the fireball, pointing the way to meteorite fragments on the ground. Given the convenient location, the searchers were even able to marshal a slow-moving zeppelin to scan the area from the air, to look for impact scars on the terrain below caused by large meteorite fragments, but none were found.
Figure 1: Meteor at Twilight. One of my coworkers knows one of my brothers I have three. My brother and this coworker are friends and their families vacation together. They happened to be at a lake one night in Northern Minnesota together and my brother showed this coworker where to look for satellites and meteors. This coworker stopped by my desk and told me about the great time they had just watching the sky and how interesting it was. I own a small cabin on a lake in Northern Minnesota. Years ago I showed my brother how to find satellites, planets, and meteors.
