They shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory, where astrometry was carried out.
[3] This minor planet was named after King Priam's herald Idaios from Greek mythology, who tells him that Paris and Menelaus want to start a duel.
[11] In the SDSS-based taxonomy, Idaios is a dark D-type asteroid, the most common type among the Jupiter trojans.
[8][12] In September 2013, the first rotational lightcurve of Idaios was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California.
Lightcurve analysis gave a rotation period of 15.733 hours with a brightness amplitude of 0.22 magnitude (U=2).
