It was discovered on 4 March 1937, by French astronomer Louis Boyer at the Algiers Observatory in Algeria, North Africa.
[14] In December 2009, a rotational lightcurve of Renauxa was obtained from photometric observations by Richard Durkee at the S.O.S.
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, Renauxa measures between 22.24 and 34.42 kilometers in diameter and its surface has an albedo between 0.09 and 0.212.
[5][6][7][8][9][10][11] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1122 and a diameter of 28.75 kilometers based on an absolute magnitude of 10.7.
[3] This minor planet was named after P. Renaux, a French astronomer and assistant at the discovering Algiers Observatory.
