Ida's [[Astronomical spectroscopy#Planets, asteroids, and comets|reflection spectrum]] was measured on 16 September 1980 by astronomers [[David J. Tholen]] and Edward F. Tedesco as part of the eight-color asteroid survey (ECAS).<ref name="ZellnerTholenTedesco1985p357p373">{{harvnb|Zellner|Tholen|Tedesco|1985|pp=357, 373}}</ref> Its spectrum matched those of the asteroids in the S-type classification.<ref>{{harvnb|Zellner|Tholen|Tedesco|1985|p=404}} {{quote|The Eos and Koronis families&nbsp;... are entirely of type S, which is rare at their heliocentric distances ...}}</ref><ref name="ZellnerTholenTedesco1985p410">{{harvnb|Zellner|Tholen|Tedesco|1985|p=410}}</ref> Many observations of Ida were made in early 1993 by the [[United States Naval Observatory Flagstaff Station|US Naval Observatory in Flagstaff]] and the [[Oak Ridge Observatory]]. These improved the measurement of Ida's orbit around the Sun and reduced the uncertainty of its position during the ''Galileo'' flyby from {{convert|78|to|60|km|mi|abbr=on}}.<ref name="OwenYeomans1994p2295">{{harvnb|Owen|Yeomans|1994|p=2295}}</ref>
