Meteorites are rocks from space that have fallen to the Earth’s surface. Once considered bad omens, they are now recognized for giving us a unique insight into the nature of the material that was present when our solar system formed.

Meteorite-Arizona01A meteorite is a solid piece of debris from a source such as an asteroid or a comet, which originates in outer space and survives its impact with the Earth’s surface. It is called a meteoroid before its impact. A meteorite’s size can range from small to extremely large. When a meteoroid enters the atmosphere, friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate that energy, thus forming a fireball, also known as a meteor or shooting/falling star. A bolide is either an extraterrestrial body that collides with the Earth, or an exceptionally bright, fireball-like meteor regardless of whether it ultimately impacts the surface.

More generally, a meteorite on the surface of any celestial body is a natural object that has come from outer space. Meteorites have been found on the moon and Mars. Meteorites that are recovered after being observed as they transit the atmosphere or impact the Earth are called meteorite fall. All other meteorites are known as finds. As of February 2010, there are approximately 1,086 witnessed falls having specimens in the world’s collections. There are more than 38,660 well-documented meteorite finds.


Meteorites have traditionally been divided into three broad categories:

  1. Stony meteorites are rocks, mainly composed of silicate minerals
  2. Iron meteorites that are largely composed of metallic iron-nickel
  3. Stony-iron meteorites that contain large amounts of both metallic and rocky material.


Modern classification schemes divide meteorites into groups according to their structure, chemical and isotopic composition and mineralogy. Meteorites smaller than 2mm are classified as micrometeorites.


Meteorite 4978SA

Meteorite4978saSince August 2005 I came into possession of a meteorite. I bought it through the internet marketplace ( by a acient store (Stormbroek Art Gallery) in Eindhoven the Netherlands. This chondrite (4978 SA) was found in the Sahara desert of North Africa and weighs 38 grams.



Meteorite from Arizona

Meteorite-arizonaDuring my vacation in September 2008 to America, I visited the meteorite crater in Arizona, where I bought this piece of meteorite. There were many pieces in the bowl but this piece caught my attention.

If you are interested you I can advise to read these books, buy your own meteorite,

or.., become a meteor hunter by yourself.
