1338 Duponta (1934 XA) is a main-belt asteroid discovered on December 4, 1934, by Boyer, L. at Algiers. Since the albedo of this asteroid is unknown, the size can only be estimated as between about 8 km - 19 km, based on the absolute magnitude (H) of 12.3.

Binary system

Photometric observations in 2007 revealed a ~3 km satellite (diameter ratio of 0.23) with an orbital period of 17.57 hours. Due to the similar size of the primary and secondary the Minor Planet Center lists this as a binary companion.
