    Phyllis is a minor planet orbiting the Sun. It is an S-type asteroid with a diameter of 38 km and a geometric albedo of 0.185. Based on photometric observations between 1998 and 2006, it has a synodic rotation period of 4.293 ± 0.001 hours. The asteroid is named after Phyllis, a character in Greek mythology.

    Violetta is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on 26 January 1905 in Heidelberg. In light of M. F. Wolf's penchant ca. 1905 for naming asteroids after operatic heroines, it is likely that 557 Violetta is named after the protagonist of Giuseppe Verdi's famous opera La Traviata.

    Carmen is a minor planet orbiting the Sun. As with a number of asteroids discovered by Max Wolf, it is named after a female character in opera, in this case the title character of Bizet's Carmen. This is classified as an M-type asteroid that spans a girth of approximately 59 km. The near infrared spectrum of this object is described as featureless. Some evidence for iron-poor orthopyroxenes on the surface has been reported.
