Hungaria (minor planet designation: 434 Hungaria) is a relatively small asteroid orbiting in the inner asteroid belt. It is an E-type (high-albedo) asteroid. It is the namesake of the Hungaria asteroids, which orbit the Sun on the inside of the 1:4 Kirkwood gap, standing out of the core of the asteroid belt.[3]
It was discovered by Max Wolf on 11 September 1898 at the University of Heidelberg. It was named after Hungary, which hosted an astronomical meeting in 1898 in Budapest.[4]
It is thought that there may be a genetic connection between 434 Hungaria and 3103 Eger and the aubrites.[4]
