    1514 Ricouxa, provisional designation 1906 UR, is a stony asteroid from the inner regions of the asteroid belt, about 7 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory in southern Germany on 22 August 1906.[10]

    The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,226 days). Its orbit is tilted by 5 degrees to the plane of the ecliptic and shows a notable eccentricity of 0.20. The body rotates around its axis once every 10.4 hours and has an albedo of 0.18 and 0.36, according to two different observations made by the Wide-field Infrared Survey Explorer.[4][5] The Collaborative Asteroid Lightcurve Link assumes an intermediate albedo of 0.24, a figure more in line with those typically found for Flora asteroids.[3]

    The minor planet was named by French astronomer André Patry (1902–1960), after whom the asteroid 1601 Patry is named. However, any reference to a person or occurrence for the name Ricouxa remains unknown.[2]
