ALH 84001 | 1.78 % by mass | which depends on its composition | 0.45 % by mass | during meteor phase | it fragments because smaller pieces with less mass are more easily slowed by the atmosphere | Antarctic meteorite | no chondrules | size is between 3 micrometers and 3 millimeters | 0.20 % by mass | 17.4 % by mass | during meteor phase which depends on composition | crater | Allan Hills, Antarctica | recorded by eyewitness or inferred from dating methods | 0.01 % by mass | | cooling in deep underground chambers | ALH 84001 | 0.01 % by mass | 1.23 % by mass | | 1993 | | during impact phase | | MWG (JSC), SI | 485755 kg | when it hits the ground which is smaller than its velocity before it enters the atmosphere | in degrees, minutes and seconds of lattitude and longitude | 52.8 % by mass | 24.6 % by mass | often minerals not found on Earth | which can over an order of magnitude greater than total mass of fragment(s) collected at the impact site | large if the fall was witnessed | | 1994 | formed by separation of molten rock in a gravity field | 0.14 % by mass | 0.02 % by mass | 1.90 kg | 1691 | meteoroid from interplanetary space or fragment dislodged from another planet, moon or planetesimal | directly proportional to initial velocity | power outages and failures in electrical equipment due to EMP (electromagnetic pulse) | very slow | prototype ALH 84001 meteorite | | 1.22 % by mass | which appears as an elongated footprint which depends on impact angle, airbursts, and impact velocity |
