3045 Alois, provisional designation Template:Mp, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 26 kilometers in diameter. The asteroid was discovered on 8 January 1984, by American astronomer Joe Wagner at Lowell's Anderson Mesa Station in Flagstaff, Arizona, United States.[1] It was named after the discoverer's grandfather Alois Stuczynski.[2]
Orbit and classification
Alois orbits the Sun in the outer main-belt at a distance of 2.8–3.5 AU once every 5 years and 6 months (2,023 days). Its orbit has an eccentricity of 0.11 and an inclination of 3° with respect to the ecliptic.[3] A first precovery was taken at Palomar Observatory in 1951, extending the body's observation arc by 33 years prior to its official discovery observation at Anderson Mesa.[1]
Physical characteristics
The C-type body is also classified as an X-type asteroid by Pan-STARRSTemplate:' large-scale survey.[4]
Rotation period
In November 2010, a rotational lightcurve of Alois was obtained from photometric observations made at the Palomar Transient Factory, California. It gave a rotation period of Script error: No such module "val". hours with a brightness amplitude of 0.18 in magnitude (U=2Script error: No such module "Check for unknown parameters".).[5]
Diameter and albedo
According to the space-based surveys by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer, Alois measures 23.5 and 27.5 kilometers in diameter, respectively, and has a corresponding albedo of 0.095 and 0.059.[6][7] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 26.6 kilometers.[8]
Naming
This minor planet was named by the discoverer in memory of his grandfather, Alois T. Stuczynski.[2] The official naming citation was published by the Minor Planet Center on 7 March 1985 (M.P.C. 9479Script error: No such module "Check for unknown parameters".).[9]
