The Moon generally rises in the eastern half of the horizon due to Earth's eastward rotation. Specifically, it rises somewhere between east-northeast and east-southeast, depending on the time of year and the Moon's phase. This variation occurs because of the Moon's monthly orbit around Earth, which shifts its path across the sky slightly each day. Similarly, the Moon sets in the western half of the horizon, varying between west-northwest and west- southwest directions
. To summarize:
- The Moon rises mostly in the east, but can range from east-northeast to east-southeast.
- The exact direction depends on the lunar phase and seasonal factors.
- This variation follows an 18.6-year cycle called the lunar standstill.
- The Moon sets generally in the west, with similar directional variation.
Therefore, if you observe the Moon rising on any given night, expect it to appear roughly in the eastern part of the horizon with some north or south offset depending on the date and lunar phase
