Eclipses occur when a planetary body blocks the Sun’s rays, consequently casting a notable
shadow, with the Sun’s rays being visible around the shadow-casting body. Two types of eclipses can be
observed from Earth: the lunar eclipse, which requires the Earth to block sunlight from the moon (giving
the moon a reddish-orange appearance) and the solar eclipse, which features the moon blocking sunlight
from the Earth (casting a shadow down on us.) Either of these phenomena require a full moon.
