1755 Lorbach, provisional designation 1936 VD, is a stony asteroid from the outer region of the asteroid belt, approximately 25 kilometers in diameter. It was discovered on 8 November 1936, by French astronomer Marguerite Laugier at Nice Observatory in southeastern France.
Lorbach orbits the Sun at a distance of 2.9–3.2 AU once every 5 years and 5 months (1,985 days). Its orbit has an eccentricity of 0.05 and an inclination of 11° with respect to the ecliptic.Lorbach was first identified as A924 PA at Heidelberg Observatory in 1924. The body's observation arc, however, begins 2 days after its official discovery observation at Nice in 1936.
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Lorbach measures 24.88 kilometers in diameter, and its surface has an albedo of 0.140. It is a stony S-type asteroid on the Tholen taxonomic scheme, and has an absolute magnitude of 10.77. As of 2017, Lorbach's spectral type, rotation period and shape remain unknown.
This minor planet was named after the maiden name of American Anne Lorbach Herget, second wife of astronomer Paul Herget, after whom the minor planet 1751 Herget is named. Anne worked as an assistant at the Cincinnati Observatory since the 1960s, key-punching MPC-data and assigning provisional designations to minor planets. Naming citation was published before November 1977 (M.P.C. 4419).
