Ascending Node
The Ascending Node (pronunciation: /əˈsɛndɪŋ noʊd/) is a term used in Astronomy and Orbital Mechanics to describe the point where an orbit crosses a reference plane, such as the ecliptic or the celestial equator, moving in a northerly direction.
Etymology
The term "Ascending Node" originates from the Latin words 'ascendere' meaning 'to climb' and 'nodus' meaning 'knot'. In the context of orbital mechanics, it refers to the point where an orbit 'climbs' from below the reference plane to above it.
