133528 Ceragioli, provisional designation Template:Mp, is an asteroid of the Koronis family from the outer regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 4 October 2003 by American astronomer David Healy at the Junk Bond Observatory in Arizona, United States. The likely stony and possibly elongated asteroid has a rotation period of 3.1 hours.[1] It was named for American optician Roger Ceragioli.[2]
Orbit and classification
Ceragioli is a member of the Koronis family (605Script error: No such module "Check for unknown parameters".),[3][4] a very large asteroid family with nearly co-planar ecliptical orbits and named after 158 Koronis.[5] It orbits the Sun in the outer asteroid belt at a distance of 2.6–3.1 AU once every 4 years and 10 months (1,764 days; semi-major axis of 2.86 AU). Its orbit has an eccentricity of 0.09 and an inclination of 1° with respect to the ecliptic.[6] The body's observation arc begins with a precovery taken by Spacewatch in September 1998, or 5 years prior to its official discovery observation at the Junk Bond Observatory.[2]
Naming
This minor planet was named after American optician Roger Ceragioli (born 1959) at the Steward Observatory Mirror Laboratory, whose projects include parts of the Bok Telescope and the MODS spectrograph for the Large Binocular Telescope. The official Template:MoMP was published by the Minor Planet Center on 1 June 2007 (M.P.C. 59925Script error: No such module "Check for unknown parameters".).[7]
Physical characteristics
Ceragioli is an assumed stony S-type asteroid,[1] in line with the overall spectral type for members of the Koronis family.[5]
Rotation period
In February 2010, a rotational lightcurve of Ceragioli was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of Script error: No such module "val". hours with a brightness variation of 0.35 magnitude (U=2Script error: No such module "Check for unknown parameters".), indicative of an elongated shape.[8] Also in February 2010, David Polishook determined a similar period of Script error: No such module "val". hours with an amplitude of 0.25 magnitude (U=1+Script error: No such module "Check for unknown parameters".).[9]
Diameter and albedo
The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 and calculates a diameter of 1.75 kilometers based on an absolute magnitude of 15.95.[1]
