The term 'solar path' is related to the 8-letter word 'analemma'. Analemma is a figure-eight pattern that is formed when plotting the position of the sun in the sky at the same time each day over the course of a year. This pattern is caused by the combination of the Earth's axial tilt and its orbital motion around the sun. The solar path is the path that the sun appears to take across the sky, which is represented by the analemma.
