In
astronomy, an
analemma (; from Greek ἀνάλημμα "support") is a diagram showing the deviation of the Sun from its mean motion in the sky, as viewed from a fixed location on the Earth. Due to the Earth's axial tilt and orbital eccentricity, the Sun will not be in the same
position in the sky at the same time every day. The north–south component of the analemma is the Sun's
declination, and the east–west component is the
equation of time. This diagram has the form of a slender figure-eight, and can often be found on
globes of the Earth.
