“27270 Guidotti”的意思、由来-开放百科全书

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.^[15]

Physical characteristics

Rotation period

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 ({{small|U=1}}).^[8] As of 2017, no secure period has been obtained.^[3]

Diameter and albedo

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 an 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.^[7]

Naming

This minor planet was named after Guido Guidotti (born 1946), an Italian amateur astronomer and founder of the Association of Astronomy "A. Pieri" ({{lang-it|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 ({{small|M.P.C. 53176}}).^[27]

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.^[15] The asteroid was named after amateur astronomer Guido Guidotti.^[2] Orbit and classification 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. 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.^[15] Physical characteristics Guidotti has been characterized as a carbonaceous C-type asteroid by Pan-STARRS photometric survey,^[10] as well as by SDSS-MFB (Masi Foglia Bus).^[3] Rotation period In March 2008, a rotational lightcurve of Guidotti was obtained from photometric observations by Slovak astronomers Adrian Galad and Leonard Kornoš.
