Moon’s Rotation and Lunar Day

The Moon’s rotation period is the same as its orbital period around the Earth, approximately 29.5 days. This means that a lunar day, from midday to midday, lasts about two weeks, with daylight lasting half and night time lasting half.

This unique rotational pattern of the Moon has significant effects on various lunar phenomena. For instance, the prolonged duration of a lunar day means that the surface experiences extreme temperature variations. During the two-week period of sunlight, lunar temperatures can rise as high as 260 degrees Fahrenheit (127 degrees Celsius), while during the two-week period of darkness, temperatures can plummet to as low as -280 degrees Fahrenheit (-173 degrees Celsius).

The Moon’s rotation and the resulting lunar day also impact the formation of lunar features such as craters and maria. As the Moon rotates, it experiences tidal forces exerted by the gravitational pull of the Earth. These tidal forces cause the Moon’s crust to flex and deform, leading to the creation of tidal bulges. Over time, the combination of tidal forces and the Moon’s rotation has influenced the distribution of lunar features, resulting in the concentration of maria on the near side of the Moon and a higher density of craters on the far side.
