The Lunar Highlands are elevated regions on the surface of the Moon, characterized by rugged terrain and numerous craters. These areas are older than the surrounding plains, known as the Maria, and are primarily composed of a type of rock called anorthosite. The highlands cover about 83% of the Moon's surface and are believed to have formed during the early history of the solar system. The Lunar Highlands are also home to many important geological features, including large impact craters like Tycho and Clavius. These highlands are significant for scientific study, as they provide insights into the Moon's formation and the history of impacts in the solar system.
