    1837 Osita, provisional designation 1971 QZ1, is a stony asteroid from the inner regions of the asteroid belt, about 8 kilometers in diameter. It was discovered on August 16, 1971 by American astronomer James B. Gibson at the Yale–Columbia Southern Station of the Leoncito Astronomical Complex in Argentina.[9]

    The main-belt asteroid is a member of the Flora family.[3] It orbits the Sun at a distance of 2.0–2.4 AU once every 3 years and 3 months (1,196 days). It has a rotation period of 3.819 hours. The geometric albedo of the S-type asteroid is in a close range of 0.19–0.20, as measured by the Akari and WISE/NEOWISE surveys, respectively.[4][5][6]

    It was named by the discoverer after his wife Ursula, of which Osita is the Spanish equivalent. She volunteered as an assistant and actively participated in the observations by measuring or reducing more than 150 positions of comets and minor planets.[2]
