It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 2 August 1949.〔 The asteroid is a member of the Flora family, one of the largest groups of asteroids in the main-belt. It orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,223 days). Its orbit shows an eccentricity of 0.19 and is tilted by 4 degrees to the plane of the ecliptic. It has a rotation period of 3.4 hours.〔〔 The S-type asteroid has a high geometric albedo of 0.28 and 0.53, determined by the WISE/NEOWISE and Akari missions.〔〔 It was named after Karel van Houten, son of Dutch astronomers Ingrid and Cornelis van Houten of the Leiden Observatory.〔 Together with Ingrid, Reinmuth discovered the minor planet 1691 Oort in 1956.
