• Chelyabinsk Meteorite

  • Location: Russia
  • Characteristics: Entered Earth's atmosphere in 2013; caused significant damage; sparked interest in near-Earth objects.

• Tissint Meteorite

  • Location: Morocco
  • Characteristics: Martian meteorite; fell in 2011; contains traces of amino acids; provides evidence of past water on Mars.

Types Of Meteorites

1. Iron Meteorites

   • Composition: Primarily made of iron and nickel.
   • Characteristics: Dense, often shiny; commonly found in deserts; examples include the Hoba and Willamette meteorites.

2. Stony Meteorites

   • Composition: Mostly silicate minerals; includes two subtypes:
     • Chondrites:
       • Characteristics: Contains round grains called chondrules; represents the oldest material in the Solar System.
     • Achondrites:
       • Characteristics: Lacks chondrules; formed from differentiated bodies.

3. Stony-Iron Meteorites

   • Composition: Mixture of both iron and silicate minerals.
   • Characteristics: Rarer than the other types; examples include the Pallasite; often show beautiful olivine crystals.

4. Carbonaceous Chondrites

   • Composition: Contains a high percentage of carbon and other volatiles.
   • Characteristics: Contains complex organic molecules; holds significant information about the early solar system.

5. Payload Meteorites

   • Composition: Rare type; consists of elements from the core and mantle of the parent body.
   • Characteristics: Provide insights into the internal structure of differentiated bodies.
