Lunar Meteorite with Photo Display Frame I A real piece of the Moon
Description: An authentic lunar meteorite in a limited edition double-sided photo-display frame. This collection quality lunar meteorite is perfect for desk or cabinet display. This is a real piece of the Moon, this is not a reproduction. Truly the gift of a lifetime. This is a lunar meteorite was ejected from our only natural satellite, and against all odds has made its way to you. This is not a tiny spec that you can barely see. This lunar specimen is large enough that you can see and appreciate it with the unaided eye. That said, we do recommend a 10x loupe for optimal viewing. This specimen has the official name of NWA 14041.
The story: Our Moon takes a lot of hits. This is evidenced by the millions of craters that cover the moon's surface. Thankfully the bombardments have slowed down considerably in the last few hundred thousand years, but they still do occur from time to time. Lunar meteorites are material ejected from our Moon's surface when it gets hit by a meteorite. If the impact has enough energy, some of the ejecta gets thrown so far it escapes the Moon's gravity becoming meteoroids hurtling through space. Some of those lunar meteoroids have the potential to eventually fall into Earth's gravity well and go screaming through the atmosphere to hit the surface. Once they hit the Earth's surface, they earn the designation of being a meteorite. Much later, perhaps thousands of years later, an even smaller fraction of the meteorites that didn't fall into the oceans or onto unrecoverable terrain, are recovered by nomads and others who happen to find them. Nothing short of miraculous odds. To describe them as rare, is perhaps an understatement.
