    1732 Heike, provisional designation 1943 EY, is a stony asteroid from the asteroid belt, about 24 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 9 March 1943.[11]

    The S-type asteroid is a member of the Eos family. It orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,911 days). Its orbit shows an eccentricity of 0.11 and is tilted by 11 degrees to the plane of the ecliptic. It has an albedo of about 0.12, based on observations carried out by IRAS, Akari, WISE and NEOWISE.[5][6][7][8]

    Photometric observations of this asteroid collected during 2008 show a rotation period of 4.74±0.01 hours with a brightness variation of 0.32±0.04 in magnitude.[10]

    It 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.[2]
