(9427) Righini is an asteroid of the main belt that was discovered on February 14, 1996 by the Italian astronomers Ulisse Munari and Maura Tombelli at the Osservatorio Astrofisico di Asiago Cima Ekar ( IAU code 098) on the Asiago plateau , 90 km northwest of Padua , has been discovered.
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.
(9427) Righini was named on July 28, 1999 after the Italian astronomer and solar physicist Guglielmo Righini (1908–1978).
