The moon is also eclipsed. Solar eclipses can occur up to five times a year, but lunar eclipses can occur up to three times a year. Just as the sun can only be on the day of the new moon , so the lunar eclipse cannot be without a full moon night. Because if there is to be an eclipse, the earth, the moon and the sun come in exactly one line. That is, during the lunar eclipse, the moon is gradually covered by a black covering and after a while it starts coming back to the illuminated state. This is called lunar eclipse.
