| meteorite fall | is a kind of meteorite |  |
| has definition a meteorite whose fall was witnessed by human or electronic means | |
| has fall date recorded by eyewitness or instruments | |
| has value higher because the fall was witnessed | |
| has fall description what witnesses saw or what was recorded by instruments | |
| has weathering negligible due to quick recovery of meteorite before corrosion begins | |
| meteorite | has fall location strewn fields, elongated footprints which depends on impact angle, airbursts, and impact velocity | |
| has fall coordinates in degrees, minutes and seconds of lattitude and longitude | |
| has fall map which appears as an elongated footprint which depends on impact angle, airbursts, and impact velocity | |
| can have crater image | |
| has original mass which can over an order of magnitude greater than total mass of fragment(s) collected at the impact site | |
| has composition often minerals not found on Earth | |
| has relative abundance | |
| has total mass of finds 485755 kg | |
| has number of finds 1691 | |
| has impact velocity when it hits the ground which is smaller than its velocity before it enters the atmosphere | |
| has impact angle | |
| has weather resistance which depends on its composition | |
| has monetary value large if the fall was witnessed | |
| has name based on the locale, region, or nearby town in which the fall occurred | |
| often produce power outages and failures in electrical equipment due to EMP (electromagnetic pulse) | |
| can be associated with crater | |
| has origin meteoroid from interplanetary space or fragment dislodged from another planet, moon or planetesimal | |
| vaporizes completely if size is between 3 micrometers and 3 millimeters | |
| can survive fall if size is larger than 3 mm and velocity is less than 24 km per second | |
| can survive fall if it fragments because smaller pieces with less mass are more easily slowed by the atmosphere | |
| has ablative mass loss depending on composition, more friable stony meteoroids loses more mass than iron meteoroid | |
| has ablative mass loss directly proportional to initial velocity | |
| can shatter during impact phase | |
| can fragment during meteor phase | |
| has fragmentation probability during meteor phase which depends on composition | |
| rock | has part mineral | |
| has texture | |
| has genesis | |
