Mackinac Island meteorite was found on Mars by the Opportunity rover on October 13, 2009.


Mackinac Island was the third of three iron meteorites encountered by the rover on Meridiani Planum within a few hundred meters, the others being Shelter Island and Block Island.[2]

Mackinac Island may have fallen on Mars in the late Noachian period and is extensively weathered.[2][5]
