![]() ![]() Moon is largely devoid of water and elements with a low boiling point as on now. It has no significant atmosphere, no erosion or weathering, no tectonic activities, rapid cooling, and low density of 3.34 g/cm 3, in comparison to Earth (5.51 g/cm 3). The lunar landscape is characterized by impact craters, their leftover ejecta, volcanoes, hills, lava flows, and depressions (Maria) filled by basaltic magma. The collision happened during the total lunar eclipse creating a number of 10–15-m deep crater. Astronomers observed that Moon was struck by an asteroid traveling at a speed of ~61,000 km an hour. The terrain is rugged due to multiple impact craters and relatively few flat lunar Maria. The far side (back dark side) is always far away from the Earth. The near side face depicts the darker area of back basalt (Maria that looks like Seas) of low in altitude and the light color Lunar Highland high in altitude ( Fig. In this process, only one side (near side) of the Moon is always visible from Earth due to Earth and Moon are in synchronous orbiting mode.
