    1788 Kiess, provisional designation 1952 OZ, is a carbonaceous asteroid from the outer region of the asteroid belt, about 21 kilometers in diameter. It was discovered by the Indiana Asteroid Program at the U.S. Goethe Link Observatory near Brooklyn, Indiana, on 25 July 1952.[7]

    The C-type asteroid is a member of the Themis family, a large group of carbonaceous outer main-belt asteroids. It orbits the Sun at a distance of 2.6–3.6 AU once every five and a half years (2,010 days). Its orbit shows an eccentricity of 0.16 and is nearly coplanar with the plane of the ecliptic, inclined by only 1 degree. It has a rotation period of 11 to 12 hours.[5][6] Based on observations by the Wide-field Infrared Survey Explorer, its albedo amounts to 0.07.[4]

    The minor planet was named for American astronomer Carl C. Kiess (1887–1967), a graduate of Indiana University, who made distinguished contributions both in astronomy and spectroscopy at the U.S. National Bureau of Standards where he worked for over 40 years. He was a member of several eclipse expeditions.[2] The lunar crater Kiess was also named in his honour.
