(6057) Robbia is an asteroid of the main outer belt that was discovered on October 16, 1977 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery took place during the 3rd Trojan survey, during which Tom Gehrels surveyed field plates recorded by the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 17 years after the start of the Palomar-Leiden- Surveys .
The mean diameter of the asteroid was calculated to be 27.43 km (± 1.9). It has a rather dark surface with an albedo of 0.0852 (± 0.013). According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel in (6057) Robbia also assumed a dark surface, so it could, roughly speaking, be be a C asteroid .
The asteroid belongs to the Cybele Group, a dynamic group of asteroids beyond the Hecuba Gap . The members' orbits are in 7: 4 resonance with the planet Jupiter , which stabilizes them. The group was named after the asteroid (65) Cybele .
(6057) Robbia was named on March 5, 1996 after the sculptor Luca della Robbia, who, along with Lorenzo Ghiberti and Donatello, was one of the founders of the early Renaissance in Florence . The asteroid of the inner main belt (6054) Ghiberti is named after Lorenzo Ghiberti, the asteroid of the middle main belt (6056) Donatello after Donatello .
