434 Hungaria is a relatively small inner Main belt asteroid. It is classified as an E-type (high-albedo) asteroid. It is the namesake for Hungaria asteroids which orbit the sun on the inside of the 1:4 Kirkwood gap, standing out of the core of the main belt.[1]
It was discovered by Max Wolf on September 11, 1898 at the University of Heidelberg. It was named after Hungary where an astronomical meeting hosted in Budapest, also in 1898.[2]
It is thought that there may be a genetic connection between 434 Hungaria and 3103 Eger and the aubrites.[2]
