(4052) Crovisier is a main belt asteroid discovered by astronomer Schelte John Bus on February 28, 1981 at the Siding Spring Observatory ( IAU code 413) near Coonabarabran , Australia .

The asteroid 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.

(4052) Crovisier was named after the French astronomer Jacques Crovisier .
