[[File:Lunar eclipse diagram-en.svg|320px|thumb|The lunar nodes are the two points where the [[orbit of the Moon|Moon's orbital path]] crosses the [[ecliptic]], the Sun's apparent yearly path on the [[celestial sphere]].]]

A '''lunar node''' is either of the two [[orbital node]]s of the [[Moon]]; that is, the two points at which the [[orbit of the Moon]] [[intersection (Euclidean geometry)|intersects]] the [[ecliptic]]. The ''ascending'' (or ''north'') node is where the Moon moves into the northern [[ecliptic coordinate system|ecliptic hemisphere]], while the ''descending'' (or ''south'') node is where the Moon enters the southern ecliptic hemisphere.
