(8761) Crane is an asteroid of the main inner belt that was discovered on March 25, 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 .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (8761) Crane determined that it could be one of the rare V-asteroids .
(8761) Crane is named after the crane ( Grus grus ), which is called Crane in English . The asteroid was named on April 2, 1999. The reason for choosing the name: When named, the population of the cranes in Europe was endangered.
