An orange moon is often called the Harvest Moon or the Hunters Moon. The Harvest Moon is the full moon that occurs closest to the autumnal equinox, while the Hunters Moon is the next full moon after the Harvest Moon. These moons are often orange in color when they are close to the horizon, and this is due to the thicker atmosphere that only allows red, orange, and yellow wavelengths to reach our eyes. An orange moon might also be caused by wildfire smoke or pollution in the air. The orange light of the Harvest Moon would glow throughout the night and allow farmers to work for more time, and these orange full moons signified the end of the summer season and the beginning of winter.
