'''34351 Decatur''' ([[Minor planet provisional designation|provisional designation]] '''{{mp|2000 RZ|8}}''') is a [[Koronis family|Koronis asteroid]] from the outer region of the [[asteroid belt]], approximately {{convert|3.5|km|mi|abbr=off|sigfig=2|sp=us}} in diameter. It was discovered on 3 September 2000, by American amateur astronomer [[Loren C. Ball|Loren Ball]] at his [[Emerald Lane Observatory]] in Alabama, United States.<ref name="MPC-object" /> The [[Q-type asteroid]] was named after the city of [[Decatur, Alabama|Decatur]], location of the discovering observatory.<ref name="springer" />

== Orbit and classification ==
Decatur is a member of the [[Koronis family]] ({{small|[[FIN tbl#605|605]]}}),<ref name="Ferret" /> a very large outer [[asteroid family]] with nearly co-planar ecliptical orbits.<ref name="Nesvorny-2014" /> It orbits the Sun in the [[Kirkwood gap|outer]] main-belt at a distance of 2.7–3.2 [[Astronomical unit|AU]] once every 5 years and 1 month (1,847 days; [[semi-major axis]] of 2.95 AU). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.07 and an [[orbital inclination|inclination]] of 1[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> The asteroid's [[observation arc]] begins 8 years prior to its official discovery observation, with a [[precovery]] taken by the [[Steward Observatory]]'s [[Spacewatch]] survey at Kitt Peak in January 1992.<ref name="MPC-object" />

== Naming ==
This [[minor planet]] was named after the city of [[Decatur, Alabama|Decatur]] in the U.S. state of Alabama, location of the discovering observatory and home of the discoverer. Decatur is located near NASA's [[Marshall Space Flight Center]].<ref name="springer" /> The official naming citation was published by the [[Minor Planet Center]] on 27 April 2002 ({{small|[[Minor Planet Circulars|M.P.C.]] 45345}}).<ref name="MPC-Circulars-Archive" />

== Physical characteristics ==
In the [[Sloan Digital Sky Survey|SDSS]]-based taxonomy, Decatur is a [[Q-type asteroid]],<ref name="Ferret" /><ref name="SDSS-Taxonomy" /> while members of the Koronis family are typically [[S-type asteroid]].<ref name="Nesvorny-2014" />{{rp|23}} According to the survey carried out by the [[NEOWISE]] mission of NASA's [[Wide-field Infrared Survey Explorer]], Decatur measures 3.54 kilometers in diameter and its surface has an [[astronomical albedo|albedo]] of 0.224.<ref name="Masiero-2011" />

=== Rotation period ===
As of 2018, no rotational [[lightcurve]] of Decatur has been obtained from [[Photometry (astronomy)|photometric]] observations. The body's [[rotation period]], [[Poles of astronomical bodies|pole]] and shape remain unknown.<ref name="jpldata" /><ref name="lcdb" />
