It was discovered on 9 March 1943, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany, and named after Heike Neckel, the granddaughter of astronomer Alfred Bohrmann. Classification and orbit The S-type asteroid is a member of the Eos family. It orbits the Sun in the outer main-belt at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,911 days). Its orbit has an eccentricity of 0.11 and an inclination of 11° with respect to the ecliptic. Heike was first identified as A906 FA at Heidelberg Observatory in 1906. The body's first used observation was also taken at Heidelberg in 1924, when it was identified as 1924 PB, extending the body's observation arc by 19 years prior to its official discovery observation. Rotation period In October 2010, a rotational lightcurve of Heike was obtained from photometric observations at the Truman Observatory. It gave a well-defined rotation period of 4.742 hours with a brightness variation of 0.32 magnitude (U=3), superseding a previous period of 3.90 hours (U=2). Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 20.50 and 24.31 kilometers in diameter, and its surface has an albedo between 0.110 and 0.201. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.132 and a diameter of 24.17 kilometers with an absolute magnitude of 10.9. Naming This minor planet was named after Heike Neckel, granddaughter of German astronomer Alfred Bohrmann (1904–2000), who was a colleague of the discoverer at Heidelberg. The asteroid 1635 Bohrmann bears his name. The official 1732 naming citation was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3933). References 2017-06-05 last obs.
