Usage: technical; astronomy; mathematics
2. of or relating to the lunar nodes (the points where the moon's orbit intersects the ecliptic)
Usage: astronomy; rare

Examples

• The nodical points of the moon's orbit are crucial for predicting eclipses.
• Nodical analysis in mathematics helps identify critical points in complex systems.
• The nodical period refers to the time it takes the moon to return to the same node.
• Engineers study nodical behavior in vibrating structures to prevent resonance.
• Astronomers track the nodical regression of the lunar orbit over time.
