8967 Calandra, provisional designation 4878 T-1, is a carbonaceous background
Cornelis van Houten at Leiden Observatory, on photographic plates taken by Dutch–American astronomer Tom Gehrels at the Palomar Observatory in California.[9] It is named after the corn bunting (Emberiza calandra).[3]
Orbit and classification
Calandra is a non-family asteroid from the main belt's
precoveries were taken prior to its discovery.[9]
Survey designation
The
Palomar–Leiden Trojan survey, named after the fruitful collaboration of the Palomar and Leiden Observatory in the 1960s and 1970s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Cornelis and Ingrid van Houten at Leiden Observatory where astrometry was carried out. The trio of astronomers are credited with the discovery of 4,620 minor planets.[10]

Diameter and albedo
According to the survey carried out by the
albedo of 0.17.[5][6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and hence calculates a larger diameter of 10.2 kilometers with an absolute magnitude of 13.54.[4]
