    1137 Raïssa is a stony background asteroid and slow rotator, approximately 22 kilometers in diameter, located in the inner regions of the asteroid belt. It was discovered by Grigory Neujmin at Simeiz Observatory in 1929, and named in memory of Raïssa Maseeva, who worked at the Pulkovo Observatory.

    Raïssa was discovered on 27 October 1929, by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula. In the following month, it was independently discovered by German Karl Reinmuth at the Heidelberg Observatory on 21 November 1929. The Minor Planet Center only acknowledges the first discoverer. The asteroid's observation arc begins at the United States Naval Observatory in December 1903, almost 26 years prior to its official discovery observation at Simeiz ...

    Raïssa is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. It orbits the Sun in the inner asteroid belt at a distance of 2.2–2.7 AU once every 3 years and 9 months. Its orbit has an eccentricity of 0.10 and an inclination of 4° with respect to the ecliptic.

    This minor planet was named in memory of Raïssa Izrailevna Maseeva, a scientific collaborator who worked at the Pulkovo Observatory. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955.

    In October 2010, a rotational lightcurve of Raïssa was obtained from photometric observations at the Bigmuskie Observatory, Italy, and the Etscorn Campus and Organ Mesa Observatory in New Mexico, United States. Lightcurve analysis gave a rotation period of 142.79 hours with ...

    In 2016, a modeled lightcurve using photometric data from various sources gave a concurring period of 143.644±0.005 hours and two spin axis of and in ecliptic coordinates.

    According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Raïssa measures between 19.421 and 23.69 kilometers in diameter and its surface has an ...
