Only 20 pallasites have been found in the U.S., but six of these were found in Missouri and Kansas. (Only 19 yellow dots appear on this map because the 20th meteorite was found in Alaska.) By longstanding convention, meteorites are named after the place that they fall or are found. The Brenham pallasite, the first pieces of which were found in Kansas in 1890, is famous for its heft — fragments found to date tip the scales at more than 4.3 metric tons. The Milton pallasite, a Missouri pallasite found in 2000, was chemically very different from other pallasites. The town of Milton is close to Conception Junction, but analysis showed the meteorites found near the two towns came from different asteroids. Credit: adapted from Google Earth, WUSTL
