If you take the picture of the sun every day from the same spot at the same time you get a looped shape known as “analemma”. 

Analemma




Since the planet Earth revolves around the Sun in an elliptical orbit and has an axial tilt, the Sun doesn’t appear at the same location every day at the same time. The analemma depicts the relative motion of the Sun with respect to a fixed location on the Earth. The analemma can be traced for not just the Sun, but also for the Moon, geosynchronous satellites and quasi-satellites.
