    Centesima is a 50 km Main-belt asteroid orbiting the Sun. It is one of the core members of the Eos family of asteroids. Relatively little is known about this tiny asteroid. It is not known to possess any natural satellites, so its mass is unknown. However, its brief rotation period of just over 5 hours implies that the body must be exceptionally dense, for its gravity is able counteract the centrifugal force. It was discovered 24 August 1903 by late-nineteenth- and early-twentieth-century astronomer Max Wolf. It was his 100th asteroid discovery, hence the name, which in Latin, means "hundredth".

    Brixia is a relatively large minor planet, specifically an asteroid orbiting mostly in the asteroid belt that was discovered by American astronomer Raymond Smith Dugan on January 10, 1904. The name derives from Brixia, the ancient name of the Italian city of Brescia.

    Sylvania is a minor planet orbiting the Sun in the main belt. It was discovered on 20 October 1903 by American astronomer R. S. Dugan at the Heidelberg observatory. The name is Latin for forest lands. 519 Sylvania is orbiting the Sun at a distance of 2.79 AU with an eccentricity (ovalness) of 0.186 and a period of 4.66 yr. The orbital plane is inclined at an angle of 11.0° to the ecliptic. This S-type (stony) asteroid has an estimated diameter of 48 km and is revolving with a period of 17.962 h.
