    1237 Geneviève, provisional designation 1931 XB, is a stony asteroid from the middle region of the asteroid belt, about 40 kilometers in diameter. It was discovered on 2 December 1931 by French astronomer Guy Reiss at Algiers Observatory, Algeria, in North Africa.[9]

    The S-type asteroid orbits the Sun at a distance of 2.4–2.8 AU once every 4 years and 3 months (1,542 days). Its orbit shows an eccentricity of 0.08 and is tilted by 10 degrees to the plane of the ecliptic. It has a rotation period of 16.4 hours, with an alternative, provisional measurement of 24.8 hours.[7][8] Based on the surveys carried out by IRAS, Akari, and WISE, its geometric albedo is between 0.04 and 0.06.[4][5][6]

    The minor planet was later named after the eldest daughter of the discoverer, Geneviève Reiss.[2] The discoverer also named the asteroids 1300 Marcelle and 1376 Michelle after two of his daughters.
