Shelter Island meteorite was found on Mars by the Opportunity rover on October 1, 2009. It is about 27 centimetres (11 in) long.[4]

History

Shelter Island was the second of three iron meteorites encountered by the rover on Meridiani Planum within a few hundred meters, the others being Block Island and Mackinac Island.[1]

Shelter Island may have fallen on Mars in the late Noachian period and is extensively weathered.[1][3]
