(8966) Hortulana is an asteroid of the main outer belt that was discovered on March 26, 1971 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery took place during the 1st 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 , eleven years after the start of the Palomar-Leiden- Surveys . There were unconfirmed sightings of the asteroid from February 3 to 6, 1954 under the provisional designation 1954 CJ at the McDonald Observatory in Texas .
The mean diameter of the asteroid was roughly calculated to be 8.905 km (± 0.431) and the albedo to be 0.067 (± 0.012).
(8966) hortulana is after Ortolan named a bird art from the family of the buntings , whose scientific name Emberiza hortulana is. At the time the asteroid was named on February 2, 1999, the gray bunting was on the Dutch and European Red List of Endangered Birds .
