undifferentiated meteorite | based on the locale, region, or nearby town in which the fall occurred | during meteor phase | when it hits the ground which is smaller than its velocity before it enters the atmosphere | meteoroid from interplanetary space or fragment dislodged from another planet, moon or planetesimal | during impact phase | less than 950 degree Celsius during its entire history since solidification | 1691 | crater | | recorded by eyewitness or inferred from dating methods | agglomeration of particles, many of which record individual, diverse histories | conglomerate | asteroid smaller than 100 km in diameter | which appears as an elongated footprint which depends on impact angle, airbursts, and impact velocity | which depends on its composition | in degrees, minutes and seconds of lattitude and longitude | during meteor phase which depends on composition | power outages and failures in electrical equipment due to EMP (electromagnetic pulse) | large if the fall was witnessed | 485755 kg | | | strewn fields, elongated footprints which depends on impact angle, airbursts, and impact velocity | it fragments because smaller pieces with less mass are more easily slowed by the atmosphere | | interstellar grains as minor inclusions | a primitive meteorite which has not been differentiated within a large asteroid | | size is between 3 micrometers and 3 millimeters | which can over an order of magnitude greater than total mass of fragment(s) collected at the impact site | | oldest and most primitive rock in solar system | often minerals not found on Earth | directly proportional to initial velocity |
