(2578) Saint-Exupéry is an asteroid of the main belt , which on November 2, 1975 by the Soviet astronomer Tamara Mikhailovna Smirnova at the Crimean Astrophysical Observatory in Nautschnyj ( IAU code 095) in the Ukraine was 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.
The asteroid was named after the French writer and aviator Antoine de Saint-Exupéry (1900–1944), who achieved worldwide fame for his story The Little Prince and was shot down on July 31, 1944 on his last reconnaissance flight.
