Hungaria group

Quick Reference

A group of asteroids at a mean distance of about 1.95 AU from the Sun, near the inner edge of the main asteroid belt but separated from it by the Kirkwood gap at the 4 : 1 resonance with Jupiter. Hungaria group members have low orbital eccentricities, but high inclinations of 22–24°. The group has been separated from the asteroid belt by the gravitational effects of the major planets, notably Jupiter, and contains a broad representation of asteroid classes. All Hungaria objects are small. The group is named after (434) Hungaria, an E-class asteroid of diameter 11.4 km, discovered in 1898 by Max Wolf. Hungaria's orbit has a semimajor axis of 1.944 AU, period 2.71 years, perihelion 1.80 AU, aphelion 2.09 AU, and inclination 22°.5.
