The largest lunar sphere on earth will lead Christie’s Deep Impact: Lunar and rare meteorites sale online until August 25. It was fashioned from a lunar meteorite — a piece of the Moon ejected into space following an impact on the lunar surface. While not one milligram of the 400kg of Apollo material is available for private ownership, some of the material returned to Earth by Apollo astronauts is remarkably similar to select lunar meteorites, including this offering. With a 98mm diameter (4 inches), this is, besides the Moon itself, the largest lunar sphere known. It is estimated at $300,000-500,000. The sale features dozens of extraterrestrial specimens and estimates are from $500.
