6793 Palazzolo, provisional designation 1991 YE, is a stony asteroid from the middle region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 30 December 1991, by Italian amateur astronomers Ulisse Quadri and Luca Strabla at the Bassano Bresciano Observatory in northern Italy. The asteroid was named after the Italian city of Palazzolo sull'Oglio.
Palazzolo orbits the Sun in the central main-belt at a distance of 2.3–3.1 AU once every 4 years and 5 months (1,603 days). Its orbit has an eccentricity of 0.16 and an inclination of 5° with respect to the ecliptic.
In 1982, the asteroid was first identified as 1982 YS2 at Crimea–Nauchnij. Its observation arc begins 1990, with its identification as 1990 SZ23 at ESO's La Silla Observatory, 1 year prior to its official discovery observation at Bassano Bresciano.
Palazzolo is an assumed S-type asteroid.
In 2012, a rotational lightcurve of Palazzolo was obtained from photometric observations at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 6.2308 hours with a brightness amplitude of 0.16 in magnitude (U=2).
