It was discovered on 28 October 1987, by Japanese astronomers Seiji Ueda and Hiroshi Kaneda at Kushiro Observatory (399) in Japan.
It orbits the Sun in the inner main-belt at a distance of 2.0–2.7 AU once every 3 years and 8 months (1,351 days).
[8] In April 2014, a rotational lightcurve of Endate was obtained from photometric observations by Hungarian astronomer Gyula M. Szabó.
Lightcurve analysis gave it a longer-than average rotation period of 34 hours with a brightness amplitude of 0.5 magnitude (U=n.a.).
[3] This minor planet was named in honor of Japanese amateur astronomer Kin Endate from Bihoro in northern Japan.
