Or for those who prefer their deviations from ideal behavior in pretty curve form, the analemma [1] captures the way in which the Sun's fails to return to the same point in the sky each day:
- The north-south component comes from the Earth's axial tilt
- The asymmetry from north to south comes from the elliptical nature of Earth's orbit, which is closer/faster in northern winter + further/slower in northern summer.
- The east-west movement comes from the equation of time, which is mostly a mix of the Earth's axial tilt and the eccentricity of its orbit.
