Web14 jan. 2024 · This happens for two reasons: the Earth’s orbit is an ellipse, rather than a circle, and the Earth is tilted with respect to the Sun. Since the Earth is rotating at a (very nearly) constant speed but is orbiting faster at some times of year than others, sometimes the Earth’s rotation is either ahead of, or is lagging behind its respective orbital in a …
