Odessa
subject			fact

Odessa	has image
	has name Odessa
	is an instance of Og octahedrite
	is an instance of type I iron meteorite
	has fall date Late Pleistocene about 50,000 years ago
	has find date 1920
	has fall location Odessa, Texas, U.S.A
	has fall coordinates Latitude 31 degrees 45 minutes 21 seconds North, Longitude 102 degrees 28 minutes 43 seconds West
	have composition 7.35% Ni, 0.48% Co, 0.25% P, 0.5% S, 0.2% C, 75 ppm Ga, 285 ppm Ge, 2 ppm Ir
	has crystal size 1.7 ±0.25 mm (coarse)
Og octahedrite	has structural class Og
type I iron meteorite	has composition kamacite, taenite, silicates, carbides
	has structural classe Om-Og octahedrite
	has total mass of finds 94688 kg
	has number of finds 69
iron meteorite	has relative abundance 5.7 % of meteorite falls
	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
structural iron meteorite	has distinguishing feature crystalline iron-nickel alloy
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 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
	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
