'''1376 Michelle''' (1935 UH) is a [[Asteroid belt|main-belt]] [[asteroid]] discovered on October 29, 1935, by [[G. Reiss]] at [[Algiers]].
'''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.<ref name="MPC-Michelle" />

The asteroid is a member of the [[Flora family]], a large group of [[S-type asteroid|S-type]] asteroids in the inner main-belt. It orbits the Sun at a distance of 1.7–2.7&nbsp;[[Astronomical unit|AU]] once every 3 years and 4 months (1,214 days). Its orbit shows a notable [[orbital eccentricity|eccentricity]] of 0.22 and is [[orbital inclination|tilted]] by 4 degrees to the plane of the [[ecliptic]]. It has a refined [[rotation period]] of 6.0 hours<ref name="Hamanowa-2009a" /><ref name="Kryszczynska-2012b" /> and an [[geometric albedo|albedo]] of about 0.26, based on observations by the space-based [[Wide-field Infrared Survey Explorer]] mission.<ref name="WISE" /><ref name="Pravec-2012b" />

The asteroid was named after the third daughter of the discoverer, Michelle Reiss.<ref name="springer" /> The discoverer also named [[1237 Geneviève]] and [[1300 Marcelle]] after two of his daughters.

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.
