'''2882 Tedesco''', provisional designation {{mp|1981 OG}}, is a Themistian asteroid from the outer regions of the asteroid belt, approximately {{convert|22|km|mi|abbr=off|sigfig=2|sp=us}} in diameter. It was discovered on 26 July 1981, by astronomer Edward Bowell at the Anderson Mesa Station near Flagstaff, Arizona.<ref name="MPC-object" /> The likely elongated C-type asteroid has a rotation period of 19.8 hours.<ref name="lcdb" /> It was named for American astronomer Ed Tedesco.<ref name="MPC-object" />
== Orbit and classification ==
''Tedesco'' is a Themistian asteroid that belongs to the Themis family ({{small|602}}),<ref name="lcdb" /><ref name="Ferret" /> one of the largest families of carbonaceous asteroids in the main belt. The family is named after its parent body 24 Themis.<ref name="Nesvorny-2014" />
''Tedesco'' orbits the Sun in the outer asteroid belt at a distance of 2.5–3.8 AU once every 5 years and 7 months (2,045 days; semi-major axis of 3.15 AU). Its orbit has an eccentricity of 0.19 and an inclination of 0° with respect to the ecliptic.<ref name="jpldata" /> The body's observation arc begins with its first observation as {{mp|1936 QG}} at Heidelberg and Konkoly Observatory in August 1936, nearly 45 years prior to its official discovery observation at Anderson Mesa.<ref name="MPC-object" />
== Physical characteristics ==
''Tedesco'' has been characterized as a carbonaceous C-type asteroid by both Pan-STARRS and SDSS,<ref name="Veres-2015" /><ref name="SDSS-Taxonomy" /> and agrees with the Themis family's overall spectral type.<ref name="Nesvorny-2014" />{{rp|23}}
=== Rotation period ===
In June 2014, a rotational lightcurve of ''Tedesco'' was obtained from photometric observations by Maurice Clark at Texas Tech's Preston Gott Observatory. Lightcurve analysis gave a well-defined rotation period of 19.805 hours with a high brightness amplitude of 0.76 magnitude, indicative of a non-spheroidal shape ({{small|U=3}}).<ref name="Clark-2015a" /> A previous measurement from October 2010 by astronomers at the Palomar Transient Factory in California gave a similar period of 19.815 with an equally high brightness variation of 0.65 magnitude.({{small|U=2}}).<ref name="Waszczak-2015" />
=== Diameter and albedo ===
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, ''Tedesco'' measures between 20.89 and 24.93 kilometers in diameter and its surface has an albedo between 0.06 and 0.084,<ref name="Nugent-2015" /><ref name="Masiero-2012" /><ref name="Nugent-2016" /> while the ''Collaborative Asteroid Lightcurve Link'' assumes an albedo of 0.08 and calculates a diameter of 21.48 kilometers based on an absolute magnitude of 11.7.<ref name="lcdb" />
== Naming ==
This minor planet was named after Edward Francis Tedesco (Ed Tedesco), a planetary scientist at the Jet Propulsion Laboratory, who analyzed observations with the Infrared Astronomical Satellite in the 1980s. His studies included photometric observations of minor planets, their pole and shape determination, as well as the compositional structure of the asteroid belt.<ref name="MPC-object" /> The official naming citation was published by the Minor Planet Center on 17 February 1984 ({{small|M.P.C. 8543}}).<ref name="MPC-Circulars-Archive" />
