Aulis is asteroid #6090 and also known as 1989 DJ. Aulis was discovered by the Belgian astronomer Henri Debehogne at the La Silla Observatory. Aulis’ orbit is characterized by a semi-major axis of 5.31 Astronomical Units, an eccentricity of 0.06, a period of revolution of 4 471 days, and an inclination of 20.2 degrees. Aulis is a Jupiter trojan of the Greek camp in Jupiter’s L₄. It is a non-family asteroid in the Jovian background population.

Aulis is named after Aulís (Αὐλίς), a port in Boetia in antiquity. The port was named after a princess of Boetia. The port Aulís (Αὐλίς) was the port, where the Greek fleet gathered to set sail for Troy and also where Agamémnōn (Ἀγαμέμνων) sacrificed his daughter Iphigéneia (Ἰφιγένεια). Aulis represents meeting points and ports in general because there is nothing so special about Aulís (Αὐλίς) that the Greek fleet couldn’t have chosen any other port as well. There also seem to be no figurative meanings.
