    1376 Michelle, provisional designation 1935 UH, is a somewhat eccentric, stony asteroid from the inner regions of the asteroid belt, about 7 kilometers in diameter. It was discovered by French astronomer Guy Reiss at the Algerian Algiers Observatory in northern Africa on 29 October 1935.[10]

    The asteroid is a member of the Flora family, a large group of S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 1.7–2.7 AU once every 3 years and 4 months (1,214 days). Its orbit shows a notable eccentricity of 0.22 and is tilted by 4 degrees to the plane of the ecliptic. It has a refined rotation period of 6.0 hours[6][9] and an albedo of about 0.26, based on observations by the space-based Wide-field Infrared Survey Explorer mission.[4][5]

    The asteroid was named after the third daughter of the discoverer, Michelle Reiss.[2] The discoverer also named 1237 Geneviève and 1300 Marcelle after two of his daughters.
