plessitic octahedrite
subject			fact

plessitic octahedrite	is a kind of octahedrite
	has structural class Opl
	has crystal size less than 0.2 mm
	has composition kamacite spindles
structural iron meteorite	has distinguishing feature crystalline iron-nickel alloy
iron meteorite	has relative abundance 5.7 % of meteorite falls
	has total mass of finds 454624 kg
	has number of finds 532
	has weather resistance high
	has fragmentation probability low because it is tougher than stony meteorite
	has ablative mass loss low because it has higher tensile strength than stony meteorite
metal-rich meteorite	has metal content higher than that of average solar system material
	has nickel content always greater than 4 %
differentiated meteorite	has origin planet or asteroid much larger than 100 km in diameter
meteorite	has fall date recorded by eyewitness or inferred from dating methods
	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 impact velocity when it hits the ground which is smaller than its velocity before it enters the atmosphere
	has impact angle
	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
	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
	can shatter during impact phase
	can fragment during meteor phase
igneous rock	has solidification mechanism
	has solidification timescale
rock	has part mineral
	has texture
	has genesis
