1753 Mieke, provisional designation 1934 JM, is a stony asteroid from the outer region of the asteroid belt, about 20 kilometers in diameter. It was discovered on 10 May 1934 by Dutch astronomer Hendrik van Gent at the Leiden Southern Station, annex to the Johannesburg Observatory in South Africa.[8]
The S-type asteroid is a member of the Eos family, thought to have formed from a catastrophic collision of its parent body resulting in more than 4,000 known members of the family. It orbits the Sun at a distance of 2.8–3.3 AU once every 5 years and 3 months (1,911 days). Its orbit shows an eccentricity of 0.08 and is tilted by 11 degrees to the plane of the ecliptic. It has a rotation period of 8.8 hours[7] and an albedo of 0.14–0.17, based on observations by the Japanese Akari and the Wide-field Infrared Survey Explorer satellites.[4][5][6]
The minor planet was named after Mieke Oort-Graadt van Roggen (1906–1993), wife of Dutch astronomy legend Jan Oort, who was director of the Leiden Observatory from 1945–1970. He had previously been honoured with the asteroid 1691 Oort.[2]
