20936 Nemrut Dagi, provisional designation 4835 T-1, is a stony asteroid from the innermost regions of the asteroid belt, approximately 3.5 kilometers in diameter. It was discovered on 13 May 1971, by Dutch astronomer couple Ingrid and Cornelis van Houten at Leiden, on photographic plates taken by Dutch–American astronomer Tom Gehrels at the Palomar Observatory in California, United States.
Nemrut Dagi as a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun in the inner main-belt at a distance of 1.7–2.0 AU once every 2 years and 6 months (922 days). Its orbit has an eccentricity of 0.10 and an inclination of 19° with respect to the ecliptic.
Due to its perihelion of less than 1.668 AU, Nemrut Dagi is classified as a Mars-crosser by the Lightcurve Data Base, while in JPL's data base, which requires a perihelion of less than 1.666 AU, the asteroid is simply an inner main-belt asteroid.
The asteroid's observation arc begins 18 years prior to its official discovery observation, with its identification 1953 CP at Palomar Observatory in February 1953.
The survey designation "T-1" stands for the first Palomar–Leiden Trojan survey, named after the fruitful collaboration of the Palomar and Leiden Observatory in the 1960s and 1970s. 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 several thousand asteroid discoveries.
