| has name Norton County | |
| is an instance of aubrite | |
| has fall date February 18, 1948, 1656 hrs | |
| has fall location Norton County, Kansas, USA | |
| has fall coordinates 39° 41' N, 99° 52' W | |
| has original mass 1-ton | |
| have composition brecciated | |
| aubrite | has letter designation AUB | |
| has characteristic mineral enstatite | |
| has total mass of finds 1205 kg | |
| has number of finds 9 | |
| has minerology enstatite, forsterite, sodic plagioclase, metal, numerous sulfides | |
| has petrology breccias of igneous lithologies | |
| has likely origin melted and crystallized residues from partial melting | |
| asteroidal achondrite | has origin asteroid | |
| highly reduced meteorite | has oxidation state highly reduced with very little FeO | |
| meteorite | has fall map which appears as an elongated footprint which depends on impact angle, airbursts, and impact velocity | |
| can have crater image | |
| has composition often minerals not found on Earth | |
| has relative abundance | |
| 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 | |
| often produce power outages and failures in electrical equipment due to EMP (electromagnetic pulse) | |
| can be associated with crater | |
| 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 | |
| achondrite | has distinguishing feature no chondrules | |
| rock | has part mineral | |
| has texture | |
| has genesis | |
| igneous rock | has solidification mechanism | |
| has solidification timescale | |
