Moon in Alphen aan den Rijn

The Moon is a fascinating celestial body, and its presence in the night sky can be observed from anywhere on Earth, including Alphen aan den Rijn, Netherlands. When the Moon is visible, its position and appearance change throughout the night as it orbits the Earth. During a full moon, the Moon’s entire face is illuminated by the Sun, making it appear as a bright, circular disc in the sky. As the Moon orbits the Earth, the amount of its illuminated surface visible from Alphen aan den Rijn gradually decreases, resulting in the waxing and waning of the Moon’s phases.

The Moon’s orbit around the Earth also affects its position in the sky. As the Moon moves through its orbit, its altitude and azimuth change, causing it to appear in different parts of the sky at different times of the night. The Moon’s altitude is measured as the angle between the horizon and the Moon’s center, while its azimuth is measured as the angle between true north and the direction to the Moon’s center. These values can be used to determine the Moon’s position in the sky and to predict its movement throughout the night.
