The term “dark side of the moon” refers to the far side of the Moon, which is permanently turned away from Earth due to tidal locking. This phenomenon occurs because the Moon’s rotational period matches its orbital period around Earth, causing the same hemisphere to always face our planet. Contrary to popular misconception, the far side receives equal amounts of sunlight as the near side and experiences regular day-night cycles.
The far side of the Moon exhibits significantly different geological characteristics compared to the near side. It contains substantially more impact craters and fewer maria (large, dark basaltic plains formed by ancient volcanic activity). The near side features approximately 31% maria coverage, while the far side contains only about 2%.
This asymmetry, known as the lunar dichotomy, results from differences in crustal thickness and composition between the two hemispheres. The far side’s terrain consists primarily of heavily cratered highlands with elevations generally higher than those on the near side. The South Pole-Aitken Basin, one of the largest impact structures in the solar system, dominates the southern portion of the far side.
This geological diversity has made the far side a target for scientific investigation, as it preserves a more complete record of early lunar bombardment and provides insights into the Moon’s formation and evolution.
