Zähringia ( minor planet designation: 421 Zähringia), provisional designation 1896 CZ, is a stony asteroid from the intermediate asteroid belt, approximately 14 kilometers in diameter. It was discovered on 7 September 1896, by astronomer Max Wolf at Heidelberg Observatory in Germany. The asteroid was named for the House of Zähringen, a medieval noble family that ruled parts of Swabia and Switzerland. [1] [2]
The first occultation of a star by 421 Zähringia was observed in 2021.
