(434) Hungaria is an asteroid of the main belt that was discovered by Max Wolf in Heidelberg on September 11, 1898 . The asteroid was named after the host country Hungary on the occasion of an astronomy congress that took place in Budapest in 1898 .
(434) Hungaria is the prototype of the asteroids of the Hungaria group : The 9: 2 orbital resonance with the planet Jupiter is characteristic of this group . The asteroids in this group have almost circular orbits (mean eccentricity 0.08) with semi-axes from 1.7 to 2 AU (i.e. in the innermost area of the asteroid belt ), which are strongly (17 ° to 27 °) inclined towards the ecliptic.
