TED-ED: The Sun's surprising movement across the sky - Gordon Williamson

The video explores the Sun's analemma, a figure-eight pattern formed by photographing the Sun at the same time each day over a year. It explains how Earth's axial tilt and orbital eccentricity contribute to this pattern. The Earth's tilt causes seasonal changes, while its elliptical orbit affects solar time, leading to discrepancies between sundials and clocks. Historical methods of timekeeping relied on the Sun's position, but modern clocks use the equation of time to adjust for these differences. The analemma's appearance varies by location and can differ on other planets due to their unique orbits and tilts.

Explain how the Earth's orbital eccentricity influences solar noon.

How does the analemma differ based on your location on Earth?
