The Smoon, consisting of one large Tectonic plate is an extinct volcano (possibly erupted/ejected from the surface of Mars and caught in the Earth's gravitational field) comprised mainly of volanic basalt, unlike the Moon, which geologists think is primarily cheese. The northern part is partly formed of limestein marine carbonates and the southern section is formed of chalk and sandstone sediments derived from strong atmospheric winds that exist on the surface of the Smoon. It was this difference between the Smoon and Moon that derived the phrase Chalk and Cheese to describe the fundamental geological differences between the two. With cheese and chalk giving different spectral signatures, this is currently the only method to find / distinguish between the two satellites. No water exists on
