In skylore, the Harvest Moon is the full moon closest to the autumn equinox. … It happens because the ecliptic – or the moon’s orbital path – makes a narrow-angle with the evening horizon near the autumn equinox. you might think the Harvest Moon looks bigger or brighter or more orange. That’s because the Harvest Moon has such a powerful mystique. Many people look for it shortly after sunset around the time of full moon. After sunset around any full moon, the moon will always be near the horizon. It’ll just have risen. It’s the location of the moon near the horizon that causes the Harvest Moon – or any full moon – to look big and orange in color.
