You wouldn't by chance be referring to the Diurnal circle...Which is the path of a celestial body during its daily apparent revolution around the earth.
The sun's diurnal circle would be a subset of this set of all possible points. What would you get if you took the globe and drew the diurnal circle for every day of the year? ... for every year, ever?
