Earth’s Axial Tilt and Orbital Plane Explained - Solar Geometry Diagram #265122 (License: Personal Use)

The image depicts the Sun on the left, connected by a horizontal line labeled “Plane of earth’s orbit” to a cross-section of Earth on the right. Earth is shown tilted on its axis (angle θ), with the North and South Poles marked, and the day side (unshaded) versus night side (dotted shading) clearly differentiated; lines A and B indicate key geometric relationships. The dashed arrow pointing “Towards north star” emphasizes the fixed orientation of Earth’s rotational axis in space.

Used in educational astronomy content, introductory planetary science courses, or科普 articles explaining seasons and celestial mechanics; matches user intent seeking visual clarification of Earth-Sun geometry and axial tilt effects.
