3045 Alois, provisional designation 1984 AW, is a carbonaceous asteroid from the outer region of the asteroid belt, about 27 kilometers in diameter. It was discovered by the astronomer J. F. Wagner at Lowell's Anderson Mesa Station in Flagstaff, Arizona, on 8 January 1984.[7]
The C-type asteroid orbits the Sun at a distance of 2.8–3.5 AU once every 5 years and 6 months (2,025 days). Its orbit is tilted by 3 degrees to the plane of the ecliptic and shows an eccentricity of 0.11. It has a rotation period of 3.753 hours[6] and an albedo of 0.06 and 0.10, as determined by the space-based Akari and WISE surveys, respectively.[4][5] The Collaborative Asteroid Lightcurve Link also assumes an albedo of 0.06, preferring the data collected by the WISE mission over the one from Akari.[3]
The minor planet was named by the discoverer in memory of his grandfather, Alois T. Stuczynski.[2]
