(8550) Hesiodos is a main outer belt asteroid discovered on August 12, 1994 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory ( IAU code 809).
The asteroid is a member of the Schubart family, a group of asteroids that was probably formed by collision 1.7 (± 0.7) billion years ago and orbits the Sun in an orbital resonance of 3: 2 with the planet Jupiter . This group is named after the asteroid (1911) Schubart .
(8550) Hesiodos was named after the Greek poet Hesiod (* before 700 BC), who told the myth of Pandora's box in his didactic poem Works and Days .
