Eye of Horus fractions were written as the sum of two or more unit fractions (a fraction with 1 as the numerator), with scribes possessing tables of answers (see Rhind Mathematical Papyrus 2/n table). Thus instead of , one would write + . Different parts of the Eye of Horus were thought to be used by the ancient Egyptians to represent one divided by the first six powers of two: The Rhind Mathematical Papyrus contains tables of "Horus Eye Fractions". Studies from the 1970s to this day in Egyptian mathematics have clearly shown this theory was fallacious and Jim Ritter definitely showed it
1924 Horus on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory where astrometry was carried out. The trio are credited with the discovery of . According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Horus" measures 12.986 kilometers in diameter and its surface has an albedo of 0.070. The body has a rotation period of 6.183 hours. This minor planet was named after Horus, the falcon-headed king of
