10656 Albrecht, also designated 2213 T-1, is a carbonaceous asteroid from the outer region of the asteroid belt, about 13 kilometers in diameter. It was discovered by Dutch astronomers Cornelis and Ingrid van Houten-Groeneveld on photographic plates taken by Dutch–American astronomer Tom Gehrels at the U.S. Palomar Observatory, California, on 25 March 1971.[5]
The dark C-type asteroid orbits the Sun at a distance of 2.9–3.5 AU once every 5 years and 8 months (2,071 days). Its orbit is tilted by 9 degrees to the plane of the ecliptic and shows an eccentricity of 0.09. It has a rotation period of 14.5 hours[4] and an albedo of 0.06, based on assumptions made by the Collaborative Asteroid Lightcurve Link (CALL).[3]
The unusual designation 2213 T–1 stands for a survey made in the search for Jupiter trojans beyond the main-belt. The team of astronomers adopted the same procedure as previously used in their fruitful and much larger Palomar–Leiden survey collaboration of the 1960s, which was named after the involved observatories at Palomar and Leiden. In both surveys, 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 of astronomers are credited with several thousand asteroid discoveries.
The minor planet was named for German astronomer Carl Theodor Albrecht (1843–1915) was influential in setting up the International Latitude Service (ILS). He became the first head of the ILS when it was established in 1899 at the Prussian Geodetic Institute, Potsdam. (M 47167) Carl Theodor Albrecht[2]
