A Scanning electron microscope (SEM) image of the a Chelyabinsk Meteor micrometeorite. The diameter of this meteorite is 160um. This micrometeorite was created by the melting of the larger meteorite, or originated as metallic particles that followed the meteorite into the Earth's atmosphere. Micrometeorites routinely fall all over the surface of earth. This is primarily an iron meteorite with small amounts of other elements. This meteorite melted from atmospheric melting as it was captured in the earths atmosphere. The frictional heating melted the martial and surface tension of the molten metals brought it to a circular shape. Magnetic iron micrometeorites are easy to find with the help of a strong magnet. The crystal structure of the meteorite is visible in this image. This micrometeorite was collected from the Chelyabinsk Meteor that entered Earth's atmosphere over Russia on 15 February 2013.
