meteorites in space

A meteorite begins its journey in the very beginning of the creation of our universe, billions of years ago, and is a remnant of the dust never a planet can grow. By the attraction of the Sun, some of these particles in orbit of the solar drawn.
The dust may clump together to fragments of different sizes but with a lump of stone with a diameter of 10 feet or greater are often referred to as an asteroid. Smaller chunks chunks are called meteoroid. Most kibble pieces are happy destroyed by the gas giant Jupiter, as the Shoemaker-Levy 9 in 1994.
When a portion of the meteoroid through the atmosphere and falls to Earth strikes are called a meteorite. The friction material is strongly heated and can be used as meteor (shooting star) are observed. The majority of the meteors associated in the atmosphere and reaches the earth. In some cases not completely burn the debris, forming a fireball and falling on Earth.
The Hamada al-Hamra is one of the 324 meteorites found in the Libyan desert near Hamada al-Hamra. The meteor is fairly stable through our atmosphere has fallen. Usually tumble the meteors through the atmosphere and get them an irregular shape. This meteorite is slightly conical shape and are melting traces on the top to see.
The type of these chondrite meteorite is called and are the oldest rocks in the solar system. The age of chondrites is known and is 4.56 billion years. Because their composition is the same though the Sun is likely that within a few million years after the birth of the solar system should be created.



Chondrites are essentially cosmic fossils and owe their name to their main ingredient: chrondrules. These are round grains that have arisen when the young solar nebula began to cool rapidly. At the rear of the Hamada al-Hamra meteorite there are a few chrondrules to see (black dots). How exactly are the chrondrules emerged to date is still a mystery.
