A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020 [update] , 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [ 1 ]

Yamato 000593 (or Y000593) is the second largest meteorite from Mars found on Earth. [2] [5] [6] Studies suggest the Martian meteorite was formed about 1.3 billion years ago from a lava flow on Mars. [7] An impact occurred on Mars about 11 million years ago [7] and ejected the meteorite from the Martian surface into space.
Nakhla meteorite's two halves, showing its inner surfaces after being broken in 1998 Nakhlites are a group of Martian meteorites , named after the first one, Nakhla meteorite . Nakhlites are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago.
Chassigny is a Martian meteorite which fell on October 3, 1815, at approximately 8:00 am, in Chassigny, north-eastern France. [2] [3] Chassigny is the meteorite for which the chassignites are named and gives rise to the "C" in the name of the SNC group of meteorites. Chassigny is an olivine cumulate rock .
Zagami is the largest single Martian meteorite ever found, weighing about 18 kilograms (40 lb). [1] It landed 10 feet (3.0 m) from a farmer near Zagami, Nigeria, and became buried in a hole about 2 feet (0.61 m) deep.
The elemental composition of Mars is different from Earth's in several significant ways. First, Martian meteorite analysis suggests that the planet's mantle is about twice as rich in iron as the Earth's mantle. [6] [7] The planet's distinctive red color is due to iron oxides on its surface. Second, its core is richer in sulphur. [8]
