2429 Schürer, provisional designation 1977 TZ, is a stony asteroid from the inner regions of the asteroid belt, about 14 kilometers in diameter. It was discovered by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland, on 12 October 1977.[9]
The Collaborative Asteroid Lightcurve Link (CALL) classifies the asteroid as a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. However, based on its concurring orbital elements, Alvarez-Candal from the Universidad Nacional de Córdoba, groups the asteroid into the Maria family, which is named after 170 Maria (also see 1996 Adams).[4]:389
It orbits the Sun at a distance of 2.3–2.8 AU once every 4 years and 1 month (1,506 days). Its orbit shows an eccentricity of 0.10 and is tilted by 15 degrees to the plane of the ecliptic. The body's rotation period has been determined by three different photometric light-curve observations, that gave a period between 6.7 and 7.5 hours.[lower-alpha 1][4][8] The asteroid's albedo amounts to 0.10–0.20, according to the surveys carried out by the Japanese Akari satellite (0.10) and the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission (0.12 and 0.20), while CALL assumes an albedo of 0.21, which results in the lowest of all estimated diameters for the body (12.1 km).[3][5][6][7]
The minor planet was named in honor of Swiss astronomer Max Schürer (1910–1997), who was director of the Astronomical Institute of the University of Bern from 1947 to 1980. Due to his initiative, endurance, and great technical competence, the discovering observatory at Zimmerwald – after which the asteroid 1775 Zimmerwald is named – could be build in 1956. He did a lot of orbit computation on asteroids when he was a pupil of astronomer Sigmund Mauderli (1876–1962), who was the preceding director of the Astronomical Institute (also see 1748 Mauderli). Schürer also dealt with stellar dynamics and was deeply involved as a pioneer in satellite geodesy.[2]
