Meteorite exploration A meteorite discovered
• After classifi cation, about 200 meteorite samples (normally weighing no more than 1g) and thin sections are loaned out every year for research by the world’s meteorite researchers.
• We loan lunar meteorites, Martian meteorites, chondrites, iron meteorites and other principal types to science museums, junior high schools, senior high schools and universities all over Japan for display or educational purposes.
