(2523) Ryba is an asteroid of the main belt , which was discovered on August 6, 1980 by the Czech astronomer Zdeňka Vávrová at the Kle Observ observatory ( observatory code 046) near the town of Český Krumlov in southern Bohemia .
The asteroid was named after the Bohemian teacher, cantor and composer of the early Romantic period Jakub Jan Ryba (1765–1815), who in 1796 created the Bohemian Christmas Mass ( Česká mše vánoční "Hej, mistře") , which was popular despite political reprisals .
(2523) Ryba belongs to the Eos family, a group of asteroids, which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
