The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon ...
A solar eclipse with small gamma will be followed by a very central total lunar eclipse. A solar eclipse where the Moon's penumbra just barely grazes the southern limb of Earth will be followed half a saros later by a lunar eclipse where the Moon just grazes the southern limb of the Earth's penumbra. [3] Tritos Equal to an inex minus a saros.
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of Earth, totally or partially.Such an alignment occurs approximately every six months, during the eclipse season in its new moon phase, when the Moon's orbital plane is closest to the plane of Earth's orbit.

The upcoming sky show is only one variety of solar eclipse. Total solar eclipses happen once every 18 months somewhere in the world—and they’re far and away the most gobsmacking type.
Central lunar eclipse is a total lunar eclipse during which the Moon passes near and through the centre of Earth's shadow, contacting the antisolar point. [11] This type of lunar eclipse is relatively rare. The relative distance of the Moon from Earth at the time of an eclipse can affect the eclipse's duration.
An eclipse season is the only time when the Sun (from the perspective of the Earth) is close enough to one of the Moon's nodes to allow an eclipse to occur. During the season, whenever there is a full moon a lunar eclipse may occur and whenever there is a new moon a solar eclipse may occur.
Viking mythology held that solar eclipses were the work of Sköll, a wolf pursuing the sun god Sol. When Sköll swallowed the sun, those on Earth made as much noise as they could to drive it off.
For each eclipse, the local surface of Earth is pointed in a different direction. The shadow of a disk held at an angle is an oval, not a circle as is seen during the eclipse. The idea of Earth being a disk is also inconsistent with the fact that a given lunar eclipse is only visible from half of Earth at a time.
