Earth’s Orbit and Seasons Explained - Solstices, Equinoxes, and Hemispheric Differences #65568 (License: Personal Use)

This vintage scientific illustration shows Earth at four critical orbital positions-June 21 (Northern summer), September 21 (autumnal equinox), December 21 (Southern summer), and March 21 (vernal equinox)-with axial tilt clearly indicated. The Sun is centered, and labels specify seasonal conditions in each hemisphere, emphasizing how tilt-not distance-causes seasons. The dotted orbit path and labeled nodes make it ideal for educational astronomy content.

Used in educational websites, science curricula, and astronomy blogs to explain seasonal mechanics; targets users seeking foundational knowledge of Earth-Sun geometry and climate cycles.
