What is the significance of a 'node' in relation to eclipses?
Answer
The point where the Moon's orbit intersects the ecliptic plane
For an eclipse to happen, the Moon must be near a node—the intersection point of its orbit and the ecliptic plane—during the New Moon (for solar) or Full Moon (for lunar) phase.
