The total or partial obscuring of one celestial body by another…

The obscuration can be either
One celestial body blocking the view to the other:
Solar eclipse---Moon blocking Earth’s view to the Sun…
One celestial body is in the shadow of another:
Lunar eclipse---Moon is in the shadow of the Earth…

The Earth and Moon cast shadows.
When either passes through the other’s shadow, we have an eclipse.

Because the Sun is an extended bright object, there are two different regions of the shadow:
Penumbra is partially illuminated
Umbra is completely dark

The lunar nodes are the orbital nodes of the Moon, that is, the points where the orbit of the Moon intersects the ecliptic path.
There are two lunar nodes which occur every Synodic month.
ascending node - where the moon crosses to the north of the ecliptic.
descending node -is where it crosses to the south.
Eclipses occur only near the lunar nodes: Solar eclipses occur when the passage of the Moon through a node coincides with the new moon .
lunar eclipses occur when passage coincides with the full moon.
For an eclipse to occur, the Moon's distance to the nodes must be less than about 1.5°.
