It was discovered on 2 April 1998, by Hungarian astronomers Krisztián Sárneczky and László Kiss at Konkoly's Piszkéstető Station northeast of Budapest, Hungary.
It orbits the Sun in the central main belt at a distance of 2.1–3.1 AU once every 4 years and 1 month (1,501 days).
[8] Horgos has been characterized as a stony S-type asteroid by PanSTARRS photometric survey.
[7] In January 2014, a rotational lightcurve of Horgos 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 3.57 hours with a brightness amplitude of 0.21 magnitude (U=2).
