Many were found in Antarctica by government search teams. Antarctica is a good place to find meteorites since they get frozen and the ice coating that never melts preserves them well. Antarctic meteorites are among the most preserved and oldest known meteorites - some of which fell as much as 700,000 years ago. Meteorites are often found by farmers in their fields and by professional meteorite hunters. The best places to find meteorites are deserts since the dry air keeps them from rusting and they stand out from earth rocks since they are usually darker than earth rocks.
Meteorites have a variety of sources where they originate.
Most are thought to come from the asteroid belt between the planet Mars and Jupiter. Interplanetary travelers and comets are another source. There are 14 rare meteorites known to be from our own Moon and 14 More from the Planet Mars. These were blasted off the surface of those parent bodies by a huge meteorite strike hundreds of thousands or even billions of years ago. The most common meteorite to Fall are stony meteorites although Irons often get found more because they look more like what people believe meteorites to look like.
