27270 Guidotti, provisional designation 2000 AY4, is a carbonaceous background asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 2 January 2000, by Italian astronomers Luciano Tesi and Alfredo Caronia at the Pistoia Mountains Astronomical Observatory in San Marcello Pistoiese, Italy. [8] The asteroid was named after amateur astronomer Guido Guidotti. [2]
Guidotti is a non-family from the main belt's background population. [4] It orbits the Sun in the inner asteroid belt at a distance of 2.3–2.6 AU once every 3 years and 10 months (1,398 days). Its orbit has an eccentricity of 0.06 and an inclination of 3° with respect to the ecliptic. [1]
The body's observation arc begins with a precovery from the Digitized Sky Survey taken at Palomar Observatory in October 1991, more than 8 years prior to its official discovery observation at San Marcello in 2000. [8]
Guidotti has been characterized as a carbonaceous C-type asteroid by Pan-STARRS photometric survey, [7] as well as by SDSS-MFB (Masi Foglia Bus). [3]
In March 2008, a rotational lightcurve of Guidotti was obtained from photometric observations by Slovak astronomers Adrian Galad and Leonard Kornoš. Analysis of the fragmentary lightcurve gave a rotation period of 2.6 hours with a brightness amplitude of 0.3 magnitude ( U=1 ). [6] As of 2017, no secure period has been obtained. [3]
Guidotti has not been observed by any of the spaced-based surveys such as the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the Japanese Akari satellite or the Infrared Astronomical Satellite.
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 3.74 kilometers based on an absolute magnitude of 14.5. [3] Based on a generic magnitude-to diameter conversion, using a typical albedo for carbonaceous asteroids of 0.06, Guidotti measures 6.9 kilometers in diameter. [5]
This minor planet was named after Guido Guidotti (born 1946), an Italian amateur astronomer and founder of the Association of Astronomy "A. Pieri" (Italian : Associazione Astrofili Valdinievole "A. Pieri"), in Valdinievole, Tuscany, Italy. He is an observer of asteroids and comets, and organizer of lectures and exhibitions on astronomical subjects. [2] The official naming citation was published by the Minor Planet Center on 26 November 2004 ( M.P.C. 53176). [9]
