(AP) – Scientists at Chicago's Field Museum are now studying a piece of the meteor that broke apart earlier this month over Michigan.

The peach-pit sized meteorite arrived Wednesday and scientists with the museum have started studying it.

NASA scientists say the originally 6-foot-wide meteor broke apart about 20 miles over Earth on January 16th. It created a bright light and what sounded like thunder in the sky.

Museum associate curator Philipp Heck believes the meteorite came from an asteroid orbiting between Mars and Jupiter. Meteorite hunter Robert Ward found it on a snow-covered lake near Hamburg, Michigan, and donated it to the Field Museum.

A meteoroid is a small chunk of asteroid or comet. When it enters Earth's atmosphere it becomes a meteor, fireball or shooting star. The pieces of rock that hit the ground are meteorites.
