(7624) Gluck is an asteroid of the main belt that was discovered on March 25, 1971 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made during the first Trojan survey , during which Tom Gehrels surveyed field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory ( IAU code 675) .
It was named after the German composer Christoph Willibald Gluck (1714–1787), who is considered one of the most important opera composers of the second half of the 18th century.
The celestial body belongs to the Eos family, a group of asteroids, which typically have large semi-axes 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.
