Student Exploration: 3d Eclipse Jun 2026

The phenomenon of an eclipse serves as a tangible demonstration of the orbital mechanics governing the Earth-Moon-Sun system. This exploration utilizes a 3D simulation environment to investigate the geometric alignment required for both solar and lunar eclipses. By manipulating variables such as orbital inclination, Moon phase, and observer position, this report elucidates why eclipses do not occur monthly. The findings confirm that the critical factor preventing frequent eclipses is the 5-degree inclination of the Moon’s orbit relative to the ecliptic plane. Eclipses are only possible during the crossing of "nodes," resulting in specific eclipse seasons.

The simulation implies the existence of "eclipse seasons." As the Earth orbits the Sun, the line of nodes (the imaginary line connecting the two orbital intersection points) eventually points toward the Sun roughly every 173 days. Only during these windows can eclipses occur, regardless of the Moon's phase. student exploration: 3d eclipse
