A super moon is when the moon orbits closest to Earth and a lunar eclipse is when the moon passes directly into Earth’s shadow giving it a reddish hue (hence the name “blood moon”). These two events occurring at the same time are extremely rare. The last time this happened was in 1982 and the next time it will happen is ‘n 2033.
