1755 Lorbach, provisional designation 1936 VD, is a stony asteroid from the outer region of the asteroid belt, about 28 kilometers in diameter. It was discovered by French astronomer Marguerite Laugier at Nice Observatory in southeastern France on 8 November 1936.[3]
The S-type asteroid orbits the Sun at a distance of 2.9–3.2 AU once every 5 years and 5 months (1,984 days). Its orbit shows an eccentricity of 0.05 and is tilted by 11 degrees to the plane of the ecliptic. It has a geometric albedo of 0.11 based on observations made by the Infrared Astronomical Satellite, IRAS.[1] Its rotation period is currently unknown.
It is 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.[2]
