The Moon is approximately 384,400 kilometers (238,855 miles) away from Earth and has a diameter of about 3,474 kilometers (2,159 miles), making it the fifth-largest moon in the solar system. Its formation is believed to have occurred about 4.5 billion years ago, shortly after the formation of Earth, likely as a result of a giant impact between Earth and a Mars-sized body named Theia.

The surface of the Moon is covered in a layer of fine dust and rocky debris called regolith, created by billions of years of meteorite impacts. These impacts have left a record of cr
