    6793 Palazzolo, provisional designation 1991 YE, is a small, stony asteroid from the middle region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered by Italian amateur astronomers Ulisse Quadri and Luca Strabla at the Bassano Bresciano Observatory, northern Italy, on 30 December 1991.[8]

    The S-type asteroid orbits the Sun at a distance of 2.3–3.1 AU once every 4 years and 5 months (1,602 days). Its orbit has an eccentricity of 0.16 and an inclination of 5° with respect to the ecliptic.[1]

    A photometric light-curve analysis from 2012, at the U.S. Palomar Transient Factory (PTF), California, gave it a rotation period of 6.2308±0.0072 hours with a brightness amplitude of 0.16 in magnitude (U=2).[5] Follow-up observations at the PTF in 2013 and 2014, rendered similar periods of 6.190±0.040 and 6.2323±0.0072 hours with an amplitude of 0.16 and 0.14, respectively (U=2).[5][6]

    According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid has a diameter of 9.9 kilometers and an albedo of 0.083,[4] while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.10 and calculates a diameter of 8.0 kilometers.[3]

    The minor planet is named after the Italian city of Palazzolo sull'Oglio, located between Brescia and Bergamo, in northern parts of the country. Known for its industries, including the first Italian factories producing cement and buttons, the city is now famous for its of spinning machines and zippers. It was founded on the banks of river Oglio, with archaeological findings dating back to the Roman era.[2]
