1912 Anubis, also designated 6534 P–L, is a stony asteroid from the outer region of the asteroid belt, about 10 kilometers in diameter. It was discovered on September 24, 1960, by the Dutch and Dutch–American astronomers Ingrid and Cornelis van Houten at Leiden, and Tom Gehrels, who took the photographic plates at Palomar Observatory, California.[5]
The S-type asteroid is a member of the Koronis family, a group consisting of about 200 known bodies. It orbits the Sun at a distance of 2.6–3.2 AU once every 4 years and 11 months (1,807 days). Its orbit shows an eccentricity of 0.09 and is tilted by 3 degrees to the plane of the ecliptic. It has a rotation period of 4.6 hours[4] and an albedo of 0.24, assumed by the Collaborative Asteroid Lightcurve Link.[3]
The designation P–L stands for Palomar–Leiden, named after Palomar and Leiden Observatory, which collaborated 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 Cornelis and Ingrid van Houten at Leiden Observatory. The trio are credited with several thousand asteroid discoveries.
The minor planet is named for Anubis, the jackal-headed Egyptian god and protector of the dead.[2] On the same date, the trio of astronomers also discovered 1923 Osiris, 1924 Horus and 5011 Ptah, also named after Ancient Egyptian deities.[6]
