A full moon occurs when the side of the Moon facing Earth is fully lit up by the Sun. There are several types of unusual full moons that look different in color and size due to its position to the Sun and Earth. These include blood moons (that appears reddish and occur during a total lunar eclipse, when Earth lines up between the Moon and the Sun); Supermoons (a moon that appears larger because it is closer to Earth), Blue Moons (the “extra” Moon in a season with four Full Moons or the second Full Moon in a calendar month) and Harvest Moons (the full, bright Moon that occurs closest to the start of Autumn)
