The Sun's Overhead Path in the Sky
As the year progresses, the sun appears to do a gradual dance across our spaces, lighting up different areas during different seasons. If you track it closely, the light tends to oscillate between two specific points, retracing its steps after a while. If mapped by noting the position of the sun in the sky at the same time from the same location, it will form a figure-eight path (called analemma by astronomers) over the course of the year. While the sun rises in the east and sets in the west every day, Earth’s elliptical path around the sun as well as its angle of tilt along its axis are what cause this gradual shift in movement in the sun’s overhead path.
