[edit] Summary

Tha asymmetry of the Earth analemma.

Source: [English Wikipedia]

(Image generated June 18, 2004 by with Gnuplot and using altitude and azimuth data generated by JPL Horizons. In this image, the analemma for planet Earth is plotted with width highly exaggerated, which permits noticing that it is very slightly asymmetrical (due to the slight eccentricity of the Earth's orbit. On November 3 the equation of time can be up to 16min 23sec fast; on February 12 it can be up to 14min 20sec slow. A similar plot can be found at http://www.analemma.com/Pages/Summation/SummationEffect/Summation.html)
