These meteorites, pieces of meteors that are found, typically range between the size of a pebble and a fist. During the decay of radioactive elements in the early history of the solar system, many asteroids melted and the iron they contained, being dense, sank to the centre to form a metallic core. One group of stony-iron meteorites, the pallasites, contains yellow-green olivine crystals encased in shiny metal. A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. Meteoroids are lumps of rock or metal that orbit the sun. They are comprised of roughly equal amounts of nickel-iron and stone and are divided into two groups: pallasites and mesosiderites.

Meteors are the streaks of light we see at night as small meteoroids burns up passing through our atmosphere (1). Meteorites are classified as chondrites on the basis of the presence within them of small spherical bodies (typically about 1 mm [0.04 inch] in diameter) called chondrules.From their shapes and the texture of the crystals in them, chondrules appear to have been free-floating molten droplets in the solar nebula.Simulation experiments show that chondrules formed by "flash" heating (to peak . Meteoroids become meteors when they crash into Earths atmosphere and the gases surrounding them briefly light up as shooting stars. While most meteors burn up and disintegrate in the atmosphere, many of these space rocks reach Earths surface in the form of meteorites. Fewer than 30 meteorites have been found since 1807. The Allende meteorite has thousands of tiny chondrules made of the mineral olivine. Achondrites contain little or Mesosiderites have a silicate portion made of mainly igneous rock fragments and are likely formed by collisions between asteroids that are rich in metal and rich in silicate.
